About

About
QA Engineer with 2+ years of experience in web and mobile testing. I have worked as a Sole QA, managing quality across 5+ projects and taking full ownership of the QA process - from requirements analysis to release decisions. I enjoy building structured QA workflows, improving product quality, and ensuring stable production releases. My experience includes functional, API, UI, and regression testing, as well as working with complex systems such as payment integrations (Stripe, PayPal) and data-driven platforms. I have hands-on experience with Postman, Charles Proxy, Swagger, Sentry, Chrome DevTools, and mobile testing tools. In my work, I focus not only on finding bugs, but also on understanding product logic, improving processes, and collaborating closely with developers, product managers, and designers. I’m currently open to new opportunities and would be happy to connect.
