Hi, I am Lenka

I have been doing QA for over five years, with a background in graphic design and frontend development. This lets me connect technical quality with UX and detail — I don't just check functionality, I think about the overall user impact. I specialise in AI-driven testing and LLM testing, where standard methodologies hit their limits.
