What I'm looking for

I’m looking to lead end-to-end QA in a fast-paced product team—building quality gates, improving API/payment reliability, and mentoring engineers—so we can ship confidently with clear processes and strong stakeholder alignment.

I’m a Senior QA Engineer / QA Lead with 5+ years of experience in web, mobile, CRM, and complex product platforms. I specialize in manual and API testing, including integrations, end-to-end quality assurance, and validating payment flows, business logic, and data consistency. I also build automation test coverage using tools like Postman and test gRPC services.

Most importantly, I lead teams and shape quality from the ground up—building QA processes, risk-based regression, bug lifecycle management, and quality gates that make releases more predictable. At Clevertec, I strengthened API quality through contract and data validation practices in Postman, reduced integration defects, and established unified standards and documentation in Confluence. I bring strong cross-functional ownership, from requirements analysis to stakeholder QA communication, mentoring, hiring, and release validation.
