I’m an AI Quality Assurance Specialist and LLM evaluation contributor with 10+ years of experience across customer experience, quality operations, and corporate training, currently based in Athens, Greece. I focus on improving AI reliability through manual QA, prompt evaluation, linguistic quality assurance, and structured testing for accuracy, consistency, tone, and cultural relevance—especially for Greek-language outputs. In my roles, I’ve built onboarding and quality processes that help teams resolve customer issues faster and coach effectively, and I enjoy turning test findings into practical feedback that makes systems smarter and safer. I also support bias detection and edge-case testing, and I collaborate to continuously refine how AI responses perform in real-world scenarios.…I’m an AI Quality Assurance Specialist and LLM evaluation contributor with 10+ years of experience across customer experience, quality operations, and corporate training, currently based in Athens, Greece.
