I'm a Senior Software QA Engineer / QA Lead with 14+ years of professional experience, including 4+ years in test automation. I help startups, SaaS companies, and established businesses deliver stable, secure, and high-quality software through structured testing, automation, and practical QA strategies.

You can expect: • Clear and actionable bug reports with reproduction steps. • Screenshots and screen recordings as evidence. • Detailed Expected vs. Actual results. • Organized test cases and execution reports. • Proactive communication and timely progress updates. • A quality-focused approach throughout the development lifecycle. I am comfortable working with distributed teams across the US, UK, Canada, Australia, and other international markets. Let's work together to improve your product quality, reduce release risks, and deliver a better user experience. Feel free to invite me to your project or send me a message to discuss your QA requirements.
