About

Engineering solutions, not just code.

I'm Adrian Dudek, a full-stack engineer with over 20 years of experience building maintainable, well-architected systems. I work across the entire stack — backend services, APIs, databases, and modern frontend interfaces.

I partner with startups and established companies to turn complex requirements into working software. Whether greenfield or legacy, I deliver pragmatic solutions that last.
