About

Software engineer based in Sofia with 10+ years of experience. I build web applications with TypeScript, React, and Node.js — but I’ve worked across the entire stack, from frontend to databases and infrastructure.

I enjoy working in environments where things move fast and every line of code brings value to users. Over the years I’ve learned that good architecture and clean code are important, but equally important are clarity, collaboration, and pragmatic decisions that keep teams moving forward.

I use Neovim btw.
