Hi, I’m Oleksandr Kozlyk, a Senior QA Automation Engineer with 4+ years of experience delivering high-quality software across mobile (iOS & Android), web, and desktop platforms in FinTech and Telecommunications. I’ve built and maintained automated regression suites using C#/.NET with Playwright and Selenium to support fast, reliable releases, and I’ve led mobile testing as a primary stream, validating critical user flows and cross‑platform behavior. I excel at ensuring data consistency between mobile clients, backend services, and APIs, and I’ve integrated automated tests into Azure DevOps CI/CD pipelines to enable continuous regression checks and release readiness. I’ve increased automated test coverage and reduced manual regression effort by prioritizing high‑risk scenarios, and I’m known for cross‑functional collaboration and clear communication within Agile teams. I’m passionate about risk-based testing, release readiness, and delivering quality in regulated, data‑sensitive environments. I enjoy shaping quality strategies across mobile, web, and desktop platforms and thrive in cross‑functional settings with developers, DevOps, product owners, and business stakeholders to drive confident releases.…Hi, I’m Oleksandr Kozlyk, a Senior QA Automation Engineer with 4+ years of experience delivering high-quality software across mobile (iOS & Android), web, and desktop platforms in FinTech and Telecommunications.
