What I'm looking for

I seek roles where I can lead QA efforts, apply shift-left practices, mentor juniors, improve processes, and collaborate with cross-functional teams to deliver high-quality user-centered products.

I am a QA Engineer with 5+ years of experience in manual, functional, API, and exploratory testing for web and mobile applications. I specialize in shift-left testing, SQL validation, and collaborating with cross-functional teams to improve QA workflows and reduce post-release defects.

I have led full QA lifecycles for international clients, mentored junior analysts, and applied test automation readiness using Playwright and Gherkin-based cases to improve regression coverage and release confidence. I prioritize user-centered quality, process improvement, and clear communication across Developers, BAs, and PMs.
