What I'm looking for

I'm looking for new challenges and the opportunity to learn new technologies.

At Use.ai, I own end-to-end QA across web applications and native iOS and Android apps. I design and execute test strategies for AI-powered features, checking behavior, output consistency, edge cases, and error handling.

At Favbet Tech, I tested game mechanics, bonus systems, sportsbook functionality, and payment flows, including cryptocurrency transactions. I analyzed transaction logs using Grafana and contributed to improving QA processes and test coverage.

At Conversionrate.store, I managed QA across concurrent projects and tested A/B experiments, prototypes, and native mobile applications. Earlier, I tested products at Edgio, Softesis Inc., and Freelancehunt, including web applications and PWAs.
