I’m a Senior QA Automation Engineer with 12+ years of experience building scalable test automation frameworks across UI, API, and performance layers. What makes me unique is my focus on test architecture and backend-heavy systems, including gRPC and service-level validation, combined with strong CI/CD integration and cloud-based testing in AWS.

I’ve led automation initiatives, mentored engineers, and worked closely with cross-functional teams to improve release quality and reliability. I’m not just focused on writing tests, but on building sustainable testing strategies that scale with the product.

I’m currently looking for a Senior/Lead SDET or QA Automation role where I can contribute to complex systems, drive quality strategy, and continue growing in a highly technical, collaborative environment.
