When I built whatsmy.fyi , I assumed I'd need a geolocation provider: MaxMind, ipinfo, ip-api, pick your poison. They all mean the same thing: an external dependency, an API key, a quota, added latency, and someone else's server seeing your users' IPs. Then I found out Cloudflare Workers makes the whole category unnecessary. The cf object Every request that hits a Cloudflare Worker carries a request.cf object, populated at the edge before your code even runs. No lookup, no latency, no key. Here's what's inside: { asn : 34984 , // ISP's autonomous system number asOrganization : " Superonline " , // ISP name city : " Istanbul " , region : " Istanbul " , country : " TR " , continent : " AS " , isEUCountry : undefined , // "1" if EU, undefined otherwise latitude : " 41.01380 " , // string, not number! longitude : " 28.94970 " , postalCode : " 34000 " , timezone : " Europe/Istanbul " , colo : " IST " , // which CF datacenter handled this clientTcpRtt : 12 , // user's RTT to the edge, in ms httpProtocol : " HTTP/3 " , tlsVersion : " TLSv1.3 " , tlsCipher : " AEAD-AES128-GCM-SHA256 " } That last group surprised me most: you get the user's HTTP protocol, TLS version, and actual TCP round-trip time for free. Try getting that from a geo API. A complete IP endpoint in ~30 lines export default { async fetch ( request ) { const cf = request . cf ?? {}; const ip = request . headers . get ( " CF-Connecting-IP " ); return Response . json ({ ip , city : cf . city ?? null , country : cf . country ?? null , isp : cf . asOrganization ?? null , asn : cf . asn ?? null , timezone : cf . timezone ?? null , lat : cf . latitude ? parseFloat ( cf . latitude ) : null , lng : cf . longitude ? parseFloat ( cf . longitude ) : null , protocol : cf . httpProtocol ?? null , tls : cf . tlsVersion ?? null , rttMs : cf . clientTcpRtt ?? null , }); }, }; That's the entire backend. No database, no GeoIP file to update monthly, no vendor. The gotchas (learned the hard way) 1. Coordinates are strings. lati

🏆 This is a submission for the June Solstice Game Jam 🎯 What I Built Turing's Frequency is a browser-based rhythm game where you decrypt encrypted radio signals by listening to musical patterns and recreating them. Each signal carries a message from a historical figure who changed the world — voices that were silenced, ignored, or forgotten, now restored through your rhythm. 🎮 👉 PLAY THE GAME LIVE 👈 📖 The Story The game is set in 1954 , on the desk of Alan Turing at the University of Manchester. A radio crackles with fragmented transmissions — encrypted messages carrying words of Pride , resistance , and identity . You are a student who has found Turing's last notebook, and with it, the key to decrypting these signals. 🌅 The connection to the June solstice: As you decrypt each signal, the screen literally brightens — from near-darkness to a flood of golden light. The solstice is the moment light and dark trade places, and this game makes that transition tangible. 🎬 Video Demo 👆 Watch the full gameplay loop: title → story → rhythm gameplay → decrypted messages → victory screen with solstice light effect. 🕹️ How to Play Key Action 1 2 3 4 Play notes ↑ ↓ ← → Arrow keys (alternative) Space / Enter Advance screens 🎧 Listen to the signal pattern 🎹 Repeat the notes in order 🔓 Decrypt the message 🌅 Restore the voice 💻 The Code The entire game is a single HTML file (~32KB) with zero external dependencies .

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built I built Academia, a modern, delivery-only Learning Management System (LMS) designed for creators who want a premium, distraction-free environment for their students. With Academia, educators can spin up their own custom academy, build out rich curriculums with video and text lessons, and securely invite students via email magic-links. Once a student accepts an invite, they are dropped into an isolated, hyper-clean student portal that tracks their course progress in real-time. This project started two years ago during a hackathon. I had this really great idea, but I was still very much a beginner. Between the tight timeframe, lack of sleep, and my slow coding speed, I just couldn't pull through to finish the project in time to submit. It sat abandoned in my repositories, gathering dust. Finishing it means finally delivering on the exact vision I had in my head two years ago, but with the skills and architecture of today. Demo Live Site Repository The Comeback Story I always told myself I’d finish this project "after the dust settles," but I never got around to it. When I saw this challenge, I knew it was time. Just looking at the 2-year-old repository gave me an instant headache. The packages were entirely outdated, Vercel was throwing massive build errors, and running npm run dev was painfully slow. Basically, everything was lagging. I seriously considered just starting a fresh repo from scratch. I figured I would just look at the shabby design I created two years ago and try to manually copy-paste the "important" code over, because I knew updating the existing mess would be an absolute nightmare. But instead, I decided to lean heavily on GitHub Copilot Auto (so I could automatically get the best models for the job) to see if we could salvage and modernize the original codebase. Here is the story of my before-and-after journey, and how Copilot helped me finally finish what I started. My Expe

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built The average student opens their notes 3 days before the exam. The above average student opens them the night before. Either way, they both end up on YouTube at 3am watching a guy explain thermodynamics with a whiteboard and too much energy. I built something better. I built Forge AI — a collaborative AI study platform that turns your lecture notes, PDFs, and YouTube links into a full study session with an AI tutor that actually talks back. Here is what it does: 📄 Upload your notes or paste a YouTube link — Forge AI reads everything and builds you a prioritised study plan in seconds. 🧠 Deep Dive into any topic — get full AI generated study notes, a mnemonic memory trick, and a built-in quiz. 🎙️ Talk to your AI tutor live — it listens, speaks back, and you can see the transcript building in real time as it talks. 👥 Create a Forge Room — invite your study group, ask the AI questions together, battle each other in a live quiz, and everyone sees everything at the same time. It started as CrammAI . A solo study tool I built under exam pressure. Well, it could generate a study plan from your uploaded files and quiz you on topics. That was it. No voice. No collaboration. No rooms. No Finesse. Just you, alone, cramming at 2am. Five months later I came back to finish it. The result is Forge AI. Demo Live app GitHub Here is what Forge AI can do: 1. Upload your materials and pick your mode Three modes based on how much time you have: 🧘 Cruise Control — 1+ week until exam 🚀 Turbo Mode — 2 days left ⚡ Zoom Mode — due tonight 2. Paste a YouTube link — it transcribes automatically ts export const apiFetchYoutubeTranscript = async ( url : string ): Promise < string > => { const videoId = extractYoutubeId ( url ); const response = await fetch ( `/api/transcript?videoId= ${ videoId } ` ); const data = await response . json (); return data . transcript ; }; No manual transcription. Paste the link, Forge AI pull

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built I built TradeWeave — a B2B + B2C fashion marketplace that connects small scale weavers and manufacturers directly to customers and retailers, eliminating middlemen entirely. The project started as a notebook idea at midnight: "What if factory workers and artisans could sell directly, keeping the full margin instead of losing 40% to supply chain bloat?" Demo 🔗 Live Demo — TradeWeave — Try it right now, no installation needed How to use: Hover over any dress card — it flips to reveal sizes Pick a size, adjust quantity, click "Add to cart" Click "Sign up" to see the premium registration flow Click the TradeWeave logo 5 times to unlock the hidden admin dashboard Click "Wholesale" tab to see direct manufacturer listings 💻 Source Code: github.com/Deeraj25/tradeweave The Comeback Story Before: Idea scribbled in a notebook at midnight Zero code written Zero deployment Tucked away under "someday projects" Status: Abandoned After: Full-featured marketplace in production ~550 lines of polished HTML/CSS/JavaScript Deployed live on Netlify + GitHub Pages Anyone can use it instantly Real product with real features Core fixes: Built the entire marketplace from scratch (this was a notebook idea, not existing code) Implemented hover-to-flip cards with CSS 3D transforms (perspective + rotateY) Created responsive product grid with auto-fill layout Built localStorage persistence for cart + admin state What Changed, Fixed, and Added Features added: 5 product categories with 20+ items Hover-flip interaction (no page reload needed) AI Try-On modal with upload UX Wholesale B2B portal with manufacturer data Hidden admin dashboard (5-click unlock) Aurora-style signup with animated hero and steps Real-time analytics dashboard (revenue, top categories, order table) Mobile-responsive design Keyboard + mouse support Polish & optimization: Custom animations (staggered reveals, floats, shimmers) Cormorant Garamond typograp

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built SpendWise AI is a free tool that audits your AI tool spending (Cursor, Copilot, Claude, ChatGPT, Gemini, Windsurf) against verified vendor pricing and tells you exactly where you're overspending and what to do about it. I originally built this as a week-long assignment for a startup. The problem it solves is simple: founders and engineering managers pay for multiple AI tools but have no idea if they're getting ripped off. SpendWise gives them that answer in under a minute, no signup needed. The interesting part is that the core audit engine has zero AI in it. It runs 6 hardcoded rules against verified pricing data, so every recommendation is reproducible and verifiable. AI (Groq's Llama 3) only kicks in to write a friendly summary paragraph on top of the structured results. I made this choice because financial recommendations need to be deterministic. Same input, same output, every time. The stack is Next.js 16, TypeScript, Tailwind + shadcn/ui, Supabase for the database, Groq for AI summaries, Resend for emails, and Vitest for testing. Deployed on Vercel. Live app: spendwise-ai-test.vercel.app Source code: github.com/Karam-999/SpendWise-AI Demo The original audit tool: The comeback (re-audit on pricing change): You can try the Round 1 version live at spendwise-ai-test.vercel.app . Pick a tool like Cursor on Teams plan at $40/mo, run the audit, and see the full savings breakdown. The Round 2 features (pricing change detection, re-audit diff view) are on a separate branch and not merged to main yet, but the demo video above walks through the complete flow. The Comeback Story Where it was: The original version was basically a calculator. You fill in your AI tools, it shows you where you can save money, and that's it. If Cursor changed its pricing the next week, your audit was already stale and you'd never know about it. It worked fine as a one-time thing. It had the form, the audit engine, AI

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built CampusBeat 2.0 — a React Native campus super-app for students across 17 colleges in Odisha, India. It started in 2023 as a simple notice board aggregator: scrape college websites so students didn't have to visit them. It worked. Students used it. Then life happened, and it sat untouched on GitHub for three years. This challenge gave me the push to finally open that repo again. What I found was equal parts embarrassing and educational. What it is now: 📰 Real-time notices for 17 colleges — ITER, KIIT, NIT Rourkela, IIT, and more 🎨 Complete UI overhaul — warm cream × charcoal × coral editorial design 🃏 3D tiltable campus identity card you can share with friends 🔖 Bookmarks — save any notice, grouped by college 💬 Real-time campus chat rooms powered by Socket.io 🛒 Campus marketplace — buy/sell within your college 🔔 Push notifications via Firebase Demo The original app from July 2023: LinkedIn post CampusBeat 2.0 — running on device: Onboarding screen - with beautiful animation Onboarding.mp4 - Google Drive drive.google.com Login screen — editorial serif heading, Lottie animation, warm ink hero Register screen — custom college picker bottom sheet with live search Home screen — quote card, college notice feed, floating tab bar Profile screen — 3D tiltable campus card with holographic shimmer Share modal — drag to rotate the card, share natively News Explorer — college chips, notice type tabs, live banner Marketplace — buy and sell within your college Bookmark - your persistent news bookmark.mp4 - Google Drive drive.google.com Chat screen - live interaction within colleges chat.mp4 - Google Drive drive.google.com The Comeback Story What I found after 3 years Opening an old repo is humbling. Here is what I walked into. The dead API. The home screen showed a daily quote — except quotable.io had shut down. Every user was silently seeing the hardcoded fallback for three years: "Villains are not bad, the

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built I built the Visual Cue Tracker, a tiny, personal sanctuary for reflection. It’s a tool designed to help us map our daily actions against our core values, specifically Empathy, Growth, and Balance. I started this project because I found myself moving so fast in my software engineering studies and internships that I often forgot why I was doing what I was doing. This tracker lets me see my week at a glance, reflect on my progress, and hold space for the things that truly matter to me. Demo Deployed site: hopebestworld.github.io github repo: https://github.com/HopeBestWorld/VisualCueTracker/tree/main demo: https://youtu.be/EqVfj289e-Q The Comeback Story When I first started this project, it was just a repo with no pushed code. In 2025, I simply set up the repo and put in a description, but never put the time or effort into bringing the idea to life. To finish it up for the challenge, I added a few things that made it feel truly alive. I built a custom, zero-key AI engine that runs entirely inside your browser. It scans your weekly reflections and gives you immediate, gentle feedback on how well your written thoughts match the values you logged. It suggests! If I’m missing the mark, it gives me specific prompts to help me get back to my goals. I added quick-export features so I can turn my weekly reflections into a clean text log, making it easy to keep a personal journal outside of the app. I set up a fully automated deployment pipeline using GitHub Actions, so my site updates instantly whenever I push my code. My Experience with GitHub Copilot GitHub Copilot felt like a supportive coding partner throughout this journey. When I was stuck on complex pathing issues for my GitHub Pages deployment, it helped me iterate through solutions quickly. It was especially great at explaining why certain parts of my code (like my custom Regex AI engine) were behaving the way they were, allowing me to stay in

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built ASTronaut is a personal code snippet manager that uses GitHub Gists as its storage backend. The name is a dumb pun: it literally builds an AST (Abstract Syntax Tree) of your Java snippets using JavaParser, pulling out class and method names so you can search by structure, not just by file name. The idea is simple: stop losing useful snippets to random notes apps or Gist pages you'll never find again. ASTronaut gives you a proper UI to create, search, edit, diff, and organize your snippets, while keeping everything synced to GitHub Gists so nothing is stuck on one machine. Frontend Repository: https://github.com/kusoroadeolu/astronaut-ui Backend Repository: https://github.com/kusoroadeolu/ASTronaut The Comeback Story The original ASTronaut had PostgreSQL, Redis, Spring Security, JWT auth, a full login/register flow, user management, admin roles, rate limiting... for a tool that only I was ever going to use. It never shipped. Not because it didn't work, but because every time I sat down to actually use it, I had to spin up a database, a Redis instance, deal with tokens. It just killed any motivation I had. The whole point was to save me time. It wasn't doing that. So it sat there. For a while. When I heard about the Finish-Up-A-Thon, this was the first project that came to mind. What Actually Changed The revamp had one goal: make it feel like a tool, not a project. Here's what got cut: The entire auth system: Spring Security, JWT, login/register, user management, all of it PostgreSQL and JPA, replaced by a lightweight local JSON index file Redis and rate limiting, pointless for a solo local tool Deep metadata extraction that was never actually used in search Here's what replaced it: GitHub PAT in an application.props file. One line of config, no OAuth flow, no callback URLs. PAT is the right call here: OAuth is for when other people are logging in with their GitHub accounts. This is just me. G

This is a submission for the June Solstice Game Jam What I Built Solstice Cipher: Enigma of the Longest Day is a browser-based puzzle game built around the Caesar cipher — the same substitution cipher technique used in ancient cryptography. On the theme of the June Solstice, I tied the longest day of the year to an Enigma Machine-inspired challenge: decode encrypted messages before time runs out, with the difficulty scaling as the sun climbs higher. The game features a real-time animated sky that shifts through dawn, noon, and dusk to reflect the solstice theme. Players are given a cipher shift key and must decode encrypted phrases by working through the Caesar cipher manually or by reasoning out the pattern — no brute-force tools allowed in-game. This connects to the June Solstice theme because the game is literally set on the longest day: the puzzles grow harder as the day progresses, and the sky animation mirrors real solstice light from sunrise to sunset. Video Demo Play it here: gtxpoffic-developer.github.io Code GTXPOFFIC-developer / Solstice-Chiper-Enigma-of-the-Longest-Day This is a Enigma based June Solstice game feel free to include your own code or tinker this project just mention the orignal developers name pls Solstice Cipher — Enigma of the Longest Day A browser-based Enigma machine puzzle game set on the June solstice.
