What I'm looking for

I'm looking for a fully remote Software QA role focused on Web/Mobile functional and regression testing, API testing, and practical test automation. I prefer flexible or APAC-friendly working hours and async collaboration. I'm open to full-time and long-term contract opportunities.

Senior Software QA Engineer with 13+ years of experience in software quality assurance and product validation, including Web, iOS, Android, API, and system-level testing.

My core strengths include functional testing, regression testing, exploratory testing, test planning, defect analysis, and cross-platform verification. I have extensive experience working closely with Engineering and Product teams to reproduce issues, identify root causes, verify fixes, and ensure product quality throughout the development lifecycle.

I also have hands-on experience with API and UI test automation using Python, pytest, and Playwright, including E2E and regression test coverage.

My earlier experience includes compatibility, performance, stress, reliability, networking, VoIP, BIOS, Windows, and Linux testing.

I am currently interested in remote Software QA opportunities involving Web/Mobile testing, API testing, functional/regression QA, and practical test automation.
