Senior Automation QA Engineer
Hi, I'm Oleksandr Serhadov
Senior Automation QA Engineer with 6+ years of experience building test automation for web and mobile products in fintech/crypto, iGaming, and e-commerce. I design automation frameworks and CI/CD pipelines end-to-end — from strategy to device labs — helping teams release faster with fewer regressions.
Currently securing core purchase and payout flows at a crypto exchange; previously led mobile automation across multiple product teams. I mentor QA engineers and drive engineering standards, including AI-assisted development practices.
