ABOUT ME
Freelancing programmer, OpenSource enthusiast and hacker based in Berlin, Germany.
Freelancing programmer, OpenSource enthusiast and hacker based in Berlin, Germany.
I am a full-stack developer with over 10 years of experience in the field, primarily front-end development but also a lot of backend-end and some systems programming experience. I'm strongest in architectural decisions, keeping code clean and small, keeping or making web-applications blazing fast, minimizing the load on browser and server.
