Ilia Usatov
Senior QA Engineer / Team Lead
Summary
Senior QA Engineer with experience in FinTech and E-commerce. Worked across the full product quality stack, including backend, API, web, and mobile testing, with hands-on experience in automation, regression strategy, release quality, and incident investigation. I combine strong technical depth with cross-functional leadership: I have led teams, driven high-impact initiatives, and improved quality visibility through metrics and observability. During a career break, I built and shipped two iOS applications, which strengthened my understanding of mobile development and the full product delivery lifecycle.
