Senior QA Engineer at Ciklum testing AI-powered features and building Playwright automation for a drone flight management system.

Ukraine

Message

At Ciklum, I test Unifly, a drone flight management system built around EU aviation regulations. I own test scope and documentation, test end-to-end flight scenarios, and analyze server-side logs to diagnose issues.

I introduced TestRail and automation frameworks that reduced overall testing time by 30% while maintaining a 95%+ defect detection rate. I also test AI-powered features for hallucinations, bias, toxicity, and behavioral drift, and I’m building a personal AI-augmented QA workflow for requirements grooming and test-case design.
