I'm Damian, a full-stack developer based near Wrocław with over 4 years of commercial experience. I enjoy shipping features end-to-end and feeling at home on both sides of the stack.
Mostly React, Next.js and TypeScript on the frontend, with Spring Boot and Java on the backend. I lean toward boring, well-supported tools that keep a team moving.
Lately my work has revolved around scalable frontend architecture in Nx monorepos, mentoring less experienced devs, and being the person who ends up doing thoughtful code reviews.
I value writing maintainable, readable code and engaging in open technical discussions — both questioning decisions and welcoming the same in return.
