Building a URL shortener with Cursor, ChatGPT, AWS Lambda, API Gateway, and Cloudflare taught me more about shipping software than writing code. Since last year, Cursor has been my go-to development assistant for daily tasks. But at the beginning of this year, just using it to generate snippets didn't feel like enough anymore. Having studied programming since 2011, I knew what modern AI tools could do, but I wanted to test their limits. I decided to build a full project—a URL shortener—without writing a single line of frontend or backend code myself. For the stack, I chose Node.js with TypeScript, React with Vite, and AWS Lambda to handle redirects. While I used ChatGPT to debate architectural trade-offs, Cursor generated the entire codebase. Watching a functional application take shape so quickly was the exact moment a line was crossed for me. It made me realize how fundamentally software development is shifting: our role is evolving from code writers to architectural decision-makers and problem-solvers. But truth be told, this project and this post represent a massive personal milestone. Like many developers, I have a graveyard of half-finished projects on my machine. This is one of the first times I've pushed a personal project all the way to production. Writing this and exposing my work to the community is a huge first step for me. This isn't just a story about code or AI—it's about the challenge of finally shipping something. The Stack Before asking Cursor to write a single line of code, I wanted to map out the architecture. I didn't need a massive enterprise system for a URL shortener, but I did want something flexible enough to support future features and experiments. To validate my ideas, I used ChatGPT to debate the pros and cons of different architectural approaches. We eventually settled on this stack: Backend: Node.js + TypeScript Frontend: React + Vite Database: MongoDB Atlas Redirects: AWS Lambda Entry Point: AWS API Gateway DNS / CDN: Cloudflare Secur

When you expose inventory or checkout endpoints to public-facing front-ends or third-party webhooks, safeguarding those APIs from brute-force scripts, scraping bots, and inventory hoarding algorithms becomes a critical requirement. Without defensive rate limiting, a single coordinated script can easily overwhelm your database connections. The Problem with Simple Counter Resets A common mistake when setting up basic API protection is using a rigid "Fixed Window" counter (e.g., allowing 100 requests per minute, resetting exactly at the turn of the clock). This creates a massive flaw where a developer can flood your server with 100 requests at 11:59:59 and another 100 requests at 12:00:01, effectively doubling your acceptable burst traffic and causing severe performance dips. To handle uneven burst traffic safely without crashing your database, the standard approach is implementing a token bucket algorithm. The Token Bucket Pattern The token bucket algorithm maintains a centralized bucket that holds a maximum capacity of tokens. Tokens are added back to the bucket at a constant, predictable rate over time. Each incoming API request consumes exactly one token. If the bucket is completely empty, the request is instantly rejected with a 429 Too Many Requests status code, protecting your core server threads. javascript // Quick Redis-based token bucket rate limiter concept async function isRateLimited(userId) { const key = `rate:${userId}`; const now = Date.now(); // Use a Redis multi-exec transaction to atomically check and update tokens const [tokens, lastRefill] = await redis.hmget(key, 'tokens', 'lastRefill'); // Calculate token replenishment based on time elapsed... // Return true if tokens <= 0, otherwise decrement tokens and update timestamp }

You asked Claude Code to add pagination to your order history endpoint. It generated a clean function — listOrdersByUser() — using a DynamoDB Scan with a Limit parameter. It compiled. Tests passed. You shipped it. Three days later your AWS bill had a line item you didn't recognize: 47 million read capacity units consumed in 72 hours. The Orders table has 50M rows. Scan reads every one of them regardless of Limit — Limit only controls how many results come back, not how many items DynamoDB reads. Claude Code didn't know your table had 50M rows. It didn't know you had a GSI on userId . It guessed, and the guess was expensive. infrawise · npm What AI Assistants Don't Know About Your Infrastructure AI coding assistants read your source files. They understand function signatures, TypeScript types, and import chains. What they cannot see is the infrastructure those functions run against. When Claude Code looks at a file that calls dynamoClient.scan({ TableName: "Orders" }) , it has no idea that: The Orders table has 50M items There is already a GSI named userId-index on the userId attribute Three other functions are already using Query against that same GSI The Sessions table is accessed by 6 separate code paths, making it a hot partition candidate Without that context, the assistant fills the gap with generic patterns. It recommends Scan because it has no reason not to. It suggests adding a GSI on status because it doesn't know one exists. It writes SELECT * because it has no idea which columns are expensive to pull. This isn't a bug in the model. It's a missing input. The model was never given your infrastructure. What Happens When infrawise Is in the Loop infrawise statically analyzes your codebase, your DynamoDB tables, and your PostgreSQL schemas, then exposes that context to your editor through MCP. Claude Code gets 15 tools that answer questions like: which tables exist, what are their partition keys and sort keys, which GSIs are already defined, which functions ar

I came to programming late — I didn't get into this world until I was past 35, and I'm 62 now, still writing code every day. This is a "build in public" post about a tool I just finished, and I'd genuinely love your feedback. The itch For years I watched infrastructure teams keep their AWS inventory in spreadsheets. It always worked — right up until it didn't. Nobody had time to keep it current, and every single one eventually drifted away from reality. Middleware EOL was the same story: a hand-maintained list, no alerts, no dashboard, quietly going stale. One day I asked the obvious question: we have tfstate, we have boto3 — why are we still doing this by hand? What I built SyncVey is a self-hosted web app that: Inventories your AWS resources into a System → Environment → Asset ledger (EC2, ECS, Lambda, RDS, S3, ALB, VPC, EBS), scanned live via boto3/AssumeRole Detects attribute-level drift between your tfstate and live AWS — including resources someone built by hand in the console that terraform plan never sees Tracks the app/middleware layer per environment and flags end-of-life runtimes The drift piece is the part I care about most. terraform plan only knows about resources Terraform already manages. The thing that actually bites teams is the resource someone spun up by hand in the console — plan is blind to it. SyncVey diffs your tfstate against the live AWS state, so those show up too. The stack (and why) Django + htmx + Postgres — server-rendered, no SPA, no Node build step MIT-licensed, no SaaS, no telemetry One docker compose up and your data stays inside your own infrastructure git clone https://github.com/MR-TABATA/SyncVey cd SyncVey docker compose up I deliberately leaned on htmx because, for a tool someone has to deploy and maintain themselves, "no frontend toolchain" matters more than a fancy client. I'd love your honest take It's AWS-only for now and very much a solo project, so I'm sure there are rough edges. I'm not an AWS specialist — I deliberatel

A few months ago I was trying to prepare for a cloud certification exam. I went looking for practice questions - good ones. Not just answer lists, but questions that actually trained the reasoning the exam tests. I found some scattered GitHub repos, a few YouTube playlists, sites with outdated question dumps. Nothing that felt structured. Nothing that explained why an answer was right, not just what it was. So I started building my own study tool. Mock questions, practice sets, AI-generated explanations. The kind of thing I wished existed. Six weeks later that became ArchReady - a certification prep platform for AWS, GCP, and PSM1. It's live now. What it does Practice questions across AWS (CCP, SAA, DVA, SAP), GCP ACE, and PSM1 Explanations for wrong answers - walks through the reasoning, not just the correct option AI-powered explanations coming soon Claude (Anthropic) Confidence tracking - shows which topics you're weak on Free to practice, no signup required. Pro unlocks full history and tracking. The stack Frontend: Next.js 14 (App Router) Backend: FastAPI (Python) AI: Claude (Anthropic) - explanations launching soon Payments: Dodo Hosting: Vercel (web) + Railway (API) Nothing exotic. I kept it boring on purpose - solo founder, 2-5 hrs/week, I can't afford interesting infrastructure problems. What I actually learned Ship before it feels ready. I had a list of 12 features I thought were "required for launch." I launched with 4. Nobody noticed the missing 8. Questions sourced from open-source + AI is good enough to start. Questions come from curated GitHub repos and AI-generated content built around official exam frameworks. That's enough to be useful. Perfection is a later problem. The hardest part isn't building - it's the first 10 users. The product exists. Getting people to try it is the actual work now. Where it is today Live at archready.io . Early stage. Still building.

No trabalho, nenhum código mudou. O que mudou foi a forma como os clientes inserem os dados. E isso quebrou coisas que nenhum teste existente pegou. O bug que só aparece quando alguém usa A motivação pra montar E2E do zero veio de um problema específico. Você precisava acessar a aplicação pra quebrar. Não era um erro de lógica isolado que um teste unitário pegaria. Era uma combinação de dados reais num fluxo real produzindo um resultado errado que só aparecia na tela. Os clientes chegavam lá antes da gente. É uma categoria de problema que teste de código não resolve, porque o problema não está no código. Está na interação entre o código, os dados e o ambiente. A forma mais rápida de pegar antes é rodar o fluxo completo do jeito que o usuário roda. Ficou com smoke tests cobrindo os principais fluxos do produto, configuração pra rodar contra múltiplos ambientes, e notificação no Slack quando o nightly quebra. A parte mais útil não são os testes em si. É saber antes do cliente reportar. Autocrop: quando nenhuma ferramenta resolve tudo Num projeto paralelo que mantenho, passei o fim de semana montando autocrop automático pra imagens. A ideia inicial era usar o imgproxy Pro, que tem detecção de objeto embutida. Não ficou preciso o suficiente pra variedade de imagens que eu tinha. Fui pro Rekognition, que retorna bounding boxes. Mais controle, mas bounding box tem um limite: é um retângulo. Objetos não são retângulos. Aí descobri o rembg, que faz algo diferente. Em vez de delimitar uma área, ele cria uma máscara pixel por pixel usando uma rede chamada U2Net, treinada pra segmentação de primeiro plano. O resultado foi bem superior — ele recorta o objeto, não uma caixa em torno dele. Colocar isso em Lambda foi onde a semana ficou mais lenta. O modelo precisava estar acessível pro processo do Lambda, coloquei em /root , Lambda não lê de lá. Movi pro /opt , chmod 755. O NUMBA tentou escrever cache em diretório read-only, defini NUMBA_CACHE_DIR=/tmp . Depois OOM em imagens mai

I built InvoiceAI an AI powered invoice generator that lets you describe what you want to invoice in plain English and get a fully formatted invoice in seconds, complete with PDF download and a real payment link. Here's how I built it for the #H0Hackathon. The Problem Freelancers and small businesses waste time manually creating invoices. You know what you did, who you did it for, and how much it costs you shouldn't have to fill out a form to capture that. The Stack - Vercel v0 — scaffolded the entire UI in one prompt Next.js 16 — framework Groq (Llama 3.3 70B) — AI natural language to invoice fields AWS DynamoDB — stores every generated invoice Paystack — generates real payment links jsPDF — client-side PDF generation Vercel — deployment How It Works User types: "50 hours of mobile app development at $80/hr for TechLagos Ltd, 7.5% VAT" Groq parses the text and extracts structured invoice data Live preview updates instantly User downloads PDF — invoice is saved to DynamoDB automatically One click generates a real Paystack payment link to send to the client Building the UI with v0 I used Vercel v0 to scaffold the entire UI in one prompt. It generated a production-ready Next.js component with a split-panel layout form on the left, live invoice preview on the right. I just had to wire up the AI and database logic. Connecting AWS DynamoDB Using the AWS SDK v3, I connected DynamoDB directly from Next.js server actions. Every time a user downloads an invoice, it's saved to DynamoDB with the client details, line items, tax rate, and timestamp. This gives the app a real data foundation that scales from day one. await dynamo . send ( new PutCommand ({ TableName : ' invoices ' , Item : { invoiceId : data . invoiceNumber , clientName : data . clientName , clientEmail : data . clientEmail , items : data . items , createdAt : new Date (). toISOString (), }, })) The Result AI generates invoice from plain English in under 2 seconds Real PDF download (no print dialog) Real Paystack

One of the first cloud concepts many people encounter while learning AWS is EC2 . The name sounds technical. The documentation is extensive. And the number of configuration options can make it feel like something fundamentally different from a regular computer. But while trying to understand cloud computing, I found myself repeatedly coming back to a simple thought: At the end of the day, an EC2 instance is just another computer. That realization helped me understand cloud infrastructure much more clearly. The Intimidation Factor When people first open the AWS console, they encounter terms such as: EC2 VPC Security Groups Elastic IPs Auto Scaling It is easy to feel that cloud computing is an entirely different world. But before diving into those concepts, it helps to ask a simpler question: What is an EC2 instance actually providing? Starting with the Name EC2 stands for: Elastic Compute Cloud The important word here is: Compute AWS is essentially renting computing resources. When you launch an EC2 instance, AWS allocates: CPU Memory (RAM) Storage Networking to a virtual machine that you can access. In other words: You are renting a computer that lives inside AWS's infrastructure. Comparing It to a Personal Computer Consider a typical laptop. It contains: A processor RAM Storage An operating system Network connectivity Now consider an EC2 instance. It also contains: Virtual CPUs RAM Storage An operating system Network connectivity The location is different. The concepts are the same. The Main Difference: Ownership The biggest difference is not technical. It is operational. With a personal computer: You own the hardware. The machine sits near you. You maintain it. With EC2: AWS owns the hardware. The machine runs in a data center. AWS manages the physical infrastructure. You only manage the virtual machine running on top of it. Why Linux Knowledge Transfers This was one of the most interesting observations during my learning. If an EC2 instance runs Linux, many of th

If you’ve ever spent hours debugging slow EC2 workloads or getting sticker shock from unexpected EBS IOPS charges, you’ve probably wondered if there’s a better storage option for temporary, high-performance data. AWS EC2 Instance Storage (also called Instance Store) is one of the most underutilized but powerful tools in the EC2 ecosystem—if you know how to use it correctly. This guide breaks down everything you need to know: core concepts, performance optimizations, use cases, limitations, and how it stacks up against EBS. By the end, you’ll be able to cut storage costs, boost workload performance, and avoid costly data loss mistakes. Table of Contents What Exactly Is AWS EC2 Instance Storage?

EC2 Instance Store is temporary block-level storage that is physically attached to the host server running your EC2 instance. Unlike standalone storage services like EBS, EFS, or S3, it is part of the EC2 service itself, with no network overhead between your instance and the storage disks. Its defining trait is its ephemeral nature: data stored on Instance Store only persists for the lifetime of the associated instance. If you stop, hibernate, or terminate your instance, all data on Instance Store volumes is permanently deleted. Core Concepts of EC2 Instance Store Before you start using Instance Store, make sure you understand these foundational rules: Device naming : Instance Store volumes are

A2A has become like a standard for enabling agent to agent communication, we could use the a2a-sdk for running and configuring the a2a server and its features such as agent card, agent skills, agent executor, request handler etc. However we are going to go with a simplified approach here with strands where the agent card will be fetched automatically. Let's get started! Server Initialize a uv project for the a2a server and switch to that directory. uv init ~/strands-a2a-server cd ~/strands-a2a-server Add the required packages. uv add python-dotenv == 1.2.2 strands-agents[a2a] == 1.42.0 Change the code in main.py to look like below. $ cat main . py from dotenv import load_dotenv from strands import Agent from strands.multiagent.a2a import A2AServer load_dotenv () def main (): agent = Agent ( callback_handler = None , description = " A sample strands agent " , model = " us.amazon.nova-micro-v1:0 " , ) a2a_server = A2AServer ( agent = agent ) a2a_server . serve () if __name__ == " __main__ " : main () I like the simplicity here, as you see above, it's quite simple to start a basic a2a server from with in strands, with just a couple of lines of code, we didn't have to install the a2a-sdk separately.

Most engineers build distributed systems hoping nothing breaks. Amazon S3 was engineered under the opposite assumption: that something is already broken, right now, and the system needs to be fine with that. That one mindset shift explains almost everything about how S3 works — and why it's one of the most reliable pieces of infrastructure on the planet. I went through a deep-dive conversation with Mai-Lan Tomsen Bukovec, VP of Data and Analytics at AWS, and extracted the engineering philosophy underneath the product. Not the marketing version. The real one. Here's what actually matters. 1. Hardware failure is not an emergency. It's Tuesday. S3 manages hundreds of exabytes of data across tens of millions of hard drives, spread across 120 Availability Zones in 38 AWS Regions. It currently stores over 500 trillion objects. At that scale, something is always failing. A disk here. A rack there. An availability zone every now and then. The math is unforgiving. So the S3 team made a deliberate architectural decision early: stop treating failure as an exception. Design it into the system as the baseline state. This means dedicated auditor and repair microservices run continuously in the background — not when something goes wrong, but always. They scan the entire fleet, inspect every byte of data, detect discrepancies, and trigger repairs automatically. No human in the loop. No incident ticket. No war room. There's also a specific property they engineer for called crash consistency — the system is designed so that after any fail-stop event, it automatically returns to a valid state without manual intervention. The failure happens. The system continues. Those two things are not in conflict. The system heals itself because it was designed to assume it's already sick. If you're building distributed systems and your failure handling is reactive — you only respond after something breaks — you've already lost. Design the repair loop as a first-class citizen, not an afterthought.

If you’re building a generative AI chatbot, global e-commerce platform, or industrial IoT solution in 2026, picking the wrong database can sink performance, blow your budget, or delay your launch. For years, teams relied on one-size-fits-all relational databases for every workload, but modern applications demand specialized tools for specific use cases. AWS solves this challenge with 15+ purpose-built database engines across 8 distinct categories, optimized for performance, scalability, and cost efficiency for every imaginable workload. This guide breaks down every AWS database type, its core features, real-world use cases, and 2026 best practices to help you choose the right tool for your next project. Table of Contents Why Purpose-Built Databases Are the Standard in 2026 AWS Database Categories: A Deep Dive 2.1 Relational Databases 2.2 Key-Value Databases 2.3 In-Memory Databases 2.4 Document Databases 2.5 Graph Databases 2.6 Wide Column Databases 2.7 Time-Series Databases 2.8 Data Warehouse 2026 AWS Database Best Practices Common Mistakes to Avoid When Choosing AWS Databases Conclusion References Why Purpose-Built Databases Are the Standard in 2026 Modern workloads have vastly different requirements: a generative AI RAG system needs fast vector search, an IoT fleet needs high-throughput time-series data ingestion, and a global SaaS platform needs multi-region consistency with zero downtime. A single relational database cannot meet all these needs without tradeoffs. AWS purpose-built databases eliminate these tradeoffs by: Supporting open standard APIs to avoid vendor lock-in Offering serverless deployment options for all major engines Including built-in AI/ML and vector search capabilities Delivering up to 99.999% availability for mission-critical workloads Reducing TCO by 25-48% compared to self-managed or generic alternatives (per IDC) AWS Database Categories: A Deep Dive Relational Databases Relational databases store data in structured tables with fixed schema

Hello everyone! It has been a busy week, but I've made some exciting progress on my machine learning journey. Here is what I've been up to: Kaggle Orbit Wars & AWS I completed the baseline implementation for the Kaggle Orbit Wars competition and initially hit a score of around 1030. My score has dipped slightly over the past few days, so I am currently brainstorming ways to improve it. This week also marked my very first time using AWS! I used it to extract data for reinforcement learning. Transparency check: I spent exactly $7.58 USD on AWS resources during the process. Paper Reading & RL Insights I spent a lot of time reading research papers this week. AlphaZero: I was initially excited about using the self-play mechanism from AlphaZero. However, because this specific game has rock-paper-scissors dynamics, standard self-play might not work effectively. AlphaStar: This led me to the AlphaStar paper, which uses self-play combined with League Training . The engineering behind AlphaStar is incredible. Two specific concepts really stood out to me: Pointer Networks and V-trace off-policy correction . I was also impressed by their use of an LSTM core to handle long-term memory. Next Steps Moving forward, I plan to leverage Kaggle, AWS, and GCP credits to train different components of my model. I am giving myself total freedom to experiment, imagine, and test unconventional solutions. Random life update to close out the week: I used to have long hair because I was insecure about my forehead, but I finally decided to shave it all off at home by myself. It honestly feels really weird right now, but it's a fresh start!

This article is a machine translation of the contents of the following URL, which I wrote in Japanese: AWS 全リージョンのデフォルト VPC を一括削除する CLI ツールを作った #Python - Qiita はじめに こんにちは、ほうき星 @H0ukiStar です。 AWS アカウントを作成すると、デフォルト VPC と呼ばれる VPC が各リージョンに 1 つずつ作成されます。 このデフォルト VPC はパブリックサブネットのみで構成されており、これらのサブネットでは E... qiita.com Introduction Hello, I’m @H0ukiStar . When you create an AWS account, a VPC called the default VPC is automatically created in each region. This default VPC consists only of public subnets, and the default subnets are configured to automatically assign public IP addresses when launching EC2 instances. When launching an EC2 instance from the AWS Management Console, this default VPC is also selected by default, which can lead to resources being created with unintended network configurations depending on your environment. For this reason, if the default VPC is not needed in your organization’s network design, some teams choose to delete it in advance as part of their operational baseline. In this article, I’ll introduce a CLI tool I created to delete default VPCs across all available regions in an AWS account. CLI Tool for Deleting Default VPCs: aws-default-vpc-cleaner The tool is available in the following repository: H0ukiStar / aws-default-vpc-cleaner A tool to delete default VPCs and related resources across all AWS regions. AWS Default VPC Cleaner A tool to delete default VPCs and related resources across all AWS regions.

Let me tell you exactly what happened the first time I tried to set up Lambda manually. Four hours. IAM trust policies I didn't fully understand, ARNs copy-pasted into the wrong fields, an API Gateway that was technically configured but somehow not routing anything correctly, and a deploy that failed with an error message pointing me nowhere useful. I hadn't written a single line of actual business logic yet. That's when someone on my team mentioned the Serverless Framework. My first reaction was honestly skepticism — another abstraction layer sounded like another thing to learn and eventually fight with. I was wrong about that. This isn't a "look how clean this tool is" post. It's more like: here's what I actually did to get a Postgres-backed CRUD API running on Lambda, step by step, including the parts that tripped me up. What the Framework Is Actually Doing Under the Hood Worth knowing before you start: the Serverless Framework isn't magic. It's generating CloudFormation templates and submitting them to AWS on your behalf. Your Lambda functions, API Gateway routes, CloudWatch log groups — all of it gets provisioned from a single config file. It works with other providers too, but the AWS integration is where it really earns its keep. The console clicking and manual ARN-wiring that burns time at the start of every serverless project? Gone. Same deploy workflow whether you're building a REST API, an event processor, or a cron job. Once you've done it once, the second project takes a fraction of the time. What You're Building Four live endpoints backed by PostgreSQL. A Users table. Create, read, update, delete — nothing exotic, but a real enough foundation that you can extend it into something actual once this guide is done. You'll need an AWS account, the AWS CLI installed, and the Serverless Framework installed before starting. That's it. Step 1: Sort Out Your AWS Credentials Run this to create both config files in one go: bash cat << EOF > ~/.aws/credentials [def

AWS disclosed that Resilient Network Graphs, a flat network architecture based on quasi-random graph theory, is now the default for most new data center builds. The design replaces fat-tree hierarchies with direct ToR-to-ToR mesh connections using passive optical ShuffleBoxes, cutting routers by 69%, boosting throughput by 33%, and reducing network power consumption by 40%.
