About Me


Hi, I’m Erfan — a full-stack developer, game programmer, part-time bug whisperer, and full-time debugger of problems I created 10 minutes ago.

I work across the stack with tools like React, Node.js, PostgreSQL, and Express, but I’ve also been known to moonlight in C++, building 2D games in SFML and a zombie apocalypse in Unreal Engine (because nothing says “stress test” like undead AI chasing you with pathfinding).

My projects are a mix of seriousness and chaos: I’ve built a Passive-Aggressive Calendar that roasts you for missing deadlines, a CropViz platform with CI pipelines and automated testing (because plants deserve data, too), and a bank fraud detection simulator that uses anomaly detection and fake transactions to make your code feel like it’s working at a fintech startup.

I’m comfortable setting up GitHub Actions for CI/CD, integrating analytics with PostHog, poking around AWS, and making sense of data using Python, NumPy, and Pandas. I also care about code readability, test coverage, and shipping features before I fall into a rabbit hole of UI micro-animations I probably didn’t need.

When I’m not coding, I’m usually reverse-engineering how other apps work, optimizing things that are probably “good enough,” or muttering “just one more commit” like it’s a bedtime story.

TL;DR: I build things, I break things, I learn fast, and I’m always ready for the next creative (or ridiculous) technical challenge.
