I build software
that ships

Hi, I'm Balázs — a developer with three years of experience across software engineering and quality assurance. I build web, desktop and AI-enabled applications with C#, React, TypeScript and Python — tested end to end, shipped through CI/CD, and equally at home on Linux, Windows or macOS.
