What I'm looking for

I’m looking for a fast-paced team where I can own manual test specifications and defect tracking, expand test automation, and work closely with cross-functional stakeholders in Agile/SDLC to deliver high-quality releases.

I’m a Senior QA Engineer with 6+ years of experience across the Software Development Life Cycle (SDLC) and Agile methodologies. I focus on translating complex business requirements into clear, detailed manual test specifications and ensuring acceptance criteria are met.

In my current role, I collaborate with cross-functional teams to ensure features ship on time while maintaining rigorous quality standards. I create and manage regression plans and test cycles, track defects in Jira, and develop/maintain automated test suites to support smoother testing transitions.

I also bring hands-on testing experience from earlier projects, including manual test execution, release support, incident resolution, and Agile ceremonies with clients and stakeholders. I’ve used tools like Cypress, Playwright, Selenium IDE, Postman/Insomnia, and SQL across unit, integration, and load testing to validate system performance and quality.
