I'm a 24-year-old full-stack developer from Warsaw, Poland 🇵🇱 with 6 years of commercial experience.
I build production-ready web applications end-to-end — from database schema to deployed frontend. My current focus is Go backends paired with Next.js, real-time systems, and clean API design.
Outside of web dev, I'm passionate about automation and robotics — I enjoy bringing software into the physical world.

- Frontend — Next.js, TypeScript, Tailwind CSS, SSR, i18n (PL/EN)
