Hey, I'm Mateusz
Software Engineer with 6+ years of commercial experience in TypeScript/Node.js, with hands-on Rust and Go in personal projects. I've been responsible for designing and implementing full production systems from the ground up — database schema, backend API, deployment. On top of that, I built internal tools that automated repetitive workflows around document processing and graphic assets. I live by Feynman's rule: "What I cannot create, I do not understand" — which is why I learn by building, not just reading.
