Backend developer building practical solutions to problems

17-year-old backend-focused developer from Poland, building practical tools for real-world problems. I work primarily with Python, with ongoing exploration into Go and C++. My projects range from system utilities to web applications — all born from personal needs and the joy of problem-solving through code.
