I lead end-to-end quality for mobile apps and SaaS platforms across APIs, infrastructure, and releases.

At AIBY, I own end-to-end quality for AI-powered B2C mobile apps across iOS, Android, backend, and web. I validate release candidates across device and OS matrices, test AI-driven features, and verify analytics, attribution, subscriptions, and paywalls.

Previously at Belitso / Allot, I owned QA for a network security SaaS platform built on Kubernetes microservices. I led and mentored up to seven QA engineers, established release-readiness criteria, and introduced BDD scenarios and automated API suites in Jenkins and GitLab CI to make regression results reproducible.

I work deeply across REST APIs, SQL and NoSQL data, performance and load testing, logs, monitoring, Docker, Helm, Linux, and Kubernetes. I prepare test environments independently and use risk-based planning to focus coverage on business impact and release risk.

At EPAM, I was a key tester for economic data-streaming applications, building TestRail coverage baselines and driving requirement clarification, feature verification, and defect reproduction with cross-functional teams.
