I'm Andras. I build the whole thing.

The first thing I built that worked was a music visualiser in 2016: a Raspberry Pi running an FFT, PWM into MOSFETs, LED strips above my bed, one burnt fingertip, and an accidental first full-stack app on top, because the lights obviously needed a web UI. Nothing in it was sophisticated, but an idea had become an object that works, and that feeling hasn't worn off since.

Most of what followed lives somewhere between a soldering iron and a browser tab. I've routed a PCB and written a 50 FPS game engine for a chip whose RAM cannot hold a single frame; built a ray tracer that generates its own shaders, then benchmarked it by walking through an electronics store; shipped one Rust merge algorithm to crates.io, npm, and PyPI; and kept 85-filter queries over 25 million properties under 100 ms by making brute force cache-friendly. The transferable part isn't a stack; it's reading the datasheet, measuring, and keeping the API small.

Professionally I'm six years in, across firmware, rendering, and AI/ML systems; my MSc thesis catalogued 33 ML deployment practices and packaged them into a Python framework. Lately AI agents write a fair share of the code: one did the SDL2 port that put my 2017 C game back online after nine years.
