Capturing, Streaming, Storing, and Visualizing Crypto Market Data in Real Time with PostgreSQL, Debezium, Kafka, JDBC & Grafana

In the fast-moving world of cryptocurrency, market data changes every second — prices fluctuate, trades execute, and volumes shift continuously. Capturing this stream of real-time data and transforming it into meaningful insights requires a robust and scalable pipeline. In this project, I built a complete real-time crypto market data pipeline that captures, streams, stores, and visualizes live data from Binance using PostgreSQL, Debezium, Kafka, JDBC, and Grafana. The goal was to design an architecture that not only moves data instantly between systems but also keeps it queryable and monitorable in real time. What began as a simple Binance data extractor evolved into a production-grade CDC (Change Data Capture) workflow capable of detecting every database change, streaming it through Kafka, storing it in a sink database, and visualizing it live on Grafana dashboards.

I am that I am.

We all hear about "Not comparing yourself to others" and that "comparing yourself is the thief of joy". To be honest, I agree and it's strange that I am contradicting myself because I compare myself A LOT. The more I looked into it, the more I realized that we have a natural tendency to compare ourselves. It's a human thing to do. The issue is that we tend to be very excessive over comparing ourselves to others to the point where it takes a toll on us. For example, we are demotivated to see someone's success because we believe we can't reach the goal they are in. We all have jealousy. Big or small. Even where I am at right now, I am still jealous that many people I know that got into big tech companies like Microsoft. To get more context, I want to share a story with you. Story Time Back in the day, I remember it was the year of the ACT. For those who don't know: It's a Standardized test that is needed for the college admissions to determine if you are admitted to their program. I remember I got a national average of 21 as my composite score and I was proud of the score I got since it's the national average during that time. However, I remember the day where my friends talked about the ACT. The most common thing I heard was: "Oh I got a 30" "I got a 32" "Man I got a 35, it was sooo easy" Hearing that makes me feel not only bummed out, but felt left out. I was feeling that I wasn't smart enough to be in the group. What's worse is that they got accepted into colleges and programs that are well known. Then they start boasting about their accomplishments. I felt like I am the odd-one-out because of my scores and their accomplishments I could not match. Why am I Talking about this? Looking back and knowing where they are at now, I am proud of who I become today. It's not that they have fallen downhill (they are still successful), but the route they have taken that I definitely could not follow. For example, on GitHub, many people fill up their contribution graphs to the

A two-pack of DJI’s most capable wireless mics just got its first price cut

Smartphones these days have incredible cameras that are capable of taking smooth, sharp video, but the microphones are often lacking, to say the least. A wireless lavalier microphone can dramatically improve the audio quality of your videos, whether you’re the only one talking, or if you’re getting audio from multiple people. The DJI Mic 3 […]

The Pixel colors might rule this year

This year's Google Pixel 11 lineup might come in a bunch of funky colors.

We've seen two sets of names for the […]
