PROFESSIONAL SUMMARY
QA Engineer with 11+ years of experience helping teams release stable, reliable products across web, mobile, API, and data-driven systems. I’m strongest when I can combine structured QA thinking with practical delivery: clarify requirements, build realistic test coverage, catch risky issues early, and keep releases under control. Alongside hands-on testing, I’ve often taken ownership of QA processes, defect triage, release readiness, and mentoring junior QAs. I’m also comfortable using modern AI-assisted tools such as Sourcegraph Cody to speed up code navigation, impact analysis, and coverage gap discovery in fast-changing products. My background includes SaaS, HR/ATS, e-commerce, healthcare IT, and high-traffic systems, with strong skills in API testing, SQL/data validation, integration testing, and cross-team quality coordination.
SELECTED ACHIEVEMENTS
• Reduced regression time from ~8 hours to ~45 minutes by improving coverage and CI execution on a multi-product e-commerce platform.
• Helped shorten regression from ~6 hours to ~1.5 hours on a high-change HR/ATS product by keeping UI and API coverage stable and scalable.
• Supported 99%+ API reliability across large integrated platforms by combining API testing, data validation, and defect triage.
• Used k6 and JMeter results to help teams identify and prioritize performance bottlenecks in systems handling 5,000+ and 10,000+ concurrent users.
• Owned and coordinated defect lifecycle for 600+ issues in Jira, including severity alignment, verification, and RCA support for critical problems.
• Mentored junior QA engineers in API testing, debugging, and practical QA ownership to improve team consistency and delivery confidence.
• Applied Sourcegraph Cody in day-to-day QA work for faster code search, impact analysis, and identifying coverage gaps.
