I spent 18 years breaking software, now I built a tool that does it faster than I ever could

I’m Liudas — a QA engineer with 18 years of experience in backend/API testing, leading QA teams in security-critical environments in the UAE.

I built Rentgen because most API bugs are simple edge cases no one has time to test manually. One cURL → hundreds of generated test cases. All local, no cloud, no telemetry.

I believe in no-nonsense engineering, fast feedback loops, and tools that help developers ship safer systems without slowing them down.

If you work with APIs — nice to meet you.
