What I'm looking for

I’m looking to lead QA automation and test strategy end-to-end—building scalable API/UI frameworks, strengthening CI/CD quality gates, and mentoring engineers in Agile delivery environments where engineering excellence and reliability matter.

I’m a Principal QA Automation Engineer and Technical Lead with more than 10 years of experience in software quality assurance and test automation. I lead QA teams, set automation strategies, and build scalable automation solutions that improve product reliability.

In my current role, I own test management and test strategy creation, develop and maintain UI and API automation frameworks, and serve as release manager. I also conduct code reviews and mentor junior automation engineers to support sustainable team growth.

My work spans API testing and UI testing, with strong emphasis on framework design, test planning, and Agile/Scrum delivery. I bring CI/CD and DevOps practices into the testing process so automation is dependable, repeatable, and ready for enterprise release cycles.

Previously, I’ve designed and standardized automation frameworks as a Senior SDET and Tech Lead, delivering CI/CD-integrated test suites and reusable components. I started by building REST services and automated test solutions, and I’ve continued evolving toward technical leadership and automation architecture.
