About

I'm a software engineer from Poland working primarily with TypeScript, Node.js, Go, React, Next.js, Hono and PostgreSQL.

I build backend systems and web applications with predictable behavior, clear boundaries and security integrated into the design.

I design and operate my own selfhosted infrastructure, giving me practical experience with Linux, Docker, networking, reverse proxies, DNS, monitoring and service administration.

I hold a Bachelor of Engineering in Computer Science from Lublin University of Technology and I am currently pursuing a Master of Engineering in Computer Science at the same university.
