What I'm looking for

I'm looking for full-time or B2B contract work, open to remote opportunities in UK or EU time zones.

At NDA, I own QA for a product with 20 developers as part of a two-person QA team, covering web, mobile, and API layers. I introduced AI-assisted QA with Claude and MCP, doubling the speed of test-case and bug-report writing.

Previously, I tested IoT, social casino, and dating products at Yalantis, Playtika, and Together Networks. My work included API and backend testing, SQL data checks, regression planning, and release testing.
