Hey, I'm Razvan — a full-stack web developer who enjoys building things end-to-end, from the UI down to the infrastructure it runs on. Most of my work has been across React/Next and NuxtJS frontends while using Express/FastAPI backends for building everything from e-commerce platforms and admin dashboards to real-time collaboration tools and trading applications.
I like getting into the details like writing custom parsers, forking libraries when they don't quite do what I need, and generally figuring out how things work under the hood rather than settling for the easy version. I've also picked up some experience along the way with IoT systems and AI/RAG applications, which has been a fun change of pace from typical web work.
