Senior QA Automation Engineer

Hi, I'm Oleksandr Serhadov

Senior QA Automation Engineer with a strong focus on building scalable, reliable, and long-term quality processes for mobile and web products. I work on end-to-end automation of critical user flows and ensure predictable, stable releases as products grow.

I develop automation ecosystems that support the full delivery lifecycle — from defining strategy and processes to enabling efficient pipelines, device coverage, and smooth release automation. My work helps teams ship faster with fewer regressions, reduced manual effort, and higher confidence in product quality.
