What I'm looking for

I’m looking for a QA role where I can own testing strategy and left-shift quality, combining API and GUI automation with Playwright, strong reporting/metrics, and close collaboration to improve release confidence.

I’m a Senior QA Engineer focused on “Developing and implementing a testing strategy” and “Left Shift Testing,” owning quality control across the lifecycle—from testing planning and coordination to the final release decision. I’ve supported releases with “over 20 regression tests” and “over 100 test runs,” while building strong coverage through “over 4,000 test cases” for positive and negative scenarios.

I bring proven impact from my quality work: “bug lifespan decreased by Agile/Scrum 60%,” I created and verified “over 2,000 bug reports,” and I helped “the number of bugs in production decreased by more than 50%” through metric analysis, defect root cause analysis, and prevention suggestions. I also develop and maintain automated tests (Playwright/Jest) and mentor Junior QA specialists, continually using end-user feedback to improve the GUI.
