About me


My name is Radoslaw Lisowski, but people call me Rado...

I build reliable code with a tester's eye for detail and a backend engineer's focus on APIs, automation, and maintainable systems. My toolkit includes Python, JavaScript, FastAPI, Pytest, Playwright, MongoDB, and CI/CD workflows.

I am currently shaping my portfolio around backend engineering, API automation, and agentic testing tools.
