✔️ 13+ years breaking software professionally
✔️ 9,000+ bugs caught before production
✔️ $100K+ potential losses prevented
✔️ 1,000+ hours of manual QA saved through automation

I’m a QA Tester / QA Engineer with 13+ years of experience in manual testing, QA automation, security testing, penetration testing support, and overall product quality assurance across web, mobile, SaaS, fintech, healthcare, cybersecurity, AI/ML, and enterprise platforms.

My work combines a strong QA mindset with practical Automation, Playwright expertise, API testing experience, and a security-focused approach. I don’t just click through screens and report obvious issues — I analyze how the product behaves, how the system is built, where integrations may fail, and where vulnerabilities may hide.
