I'm a junior Python backend developer and a fourth-year Computer Science student at PJATK in Warsaw. I mostly write Python: REST APIs and backend systems, data pipelines and some applied AI. I like clean architecture and tests, and I prefer projects that solve a real problem.
Looking for a junior backend / Python developer role or internship in Warsaw or remote.
