Senior Full Stack Developer & Computer Scientist

Senior full stack developer based in Germany, holding a Master's degree in Computer Science from HTW Berlin. I love building things, from low level hardware circuits as a self taught hobbyist to web and mobile apps as a professional developer. For me, programming is about clean logic, great tooling and creating powerful and beautiful UI/UX.
