PROFESSIONAL SUMMARY
Senior QA Engineer and QA Lead with 4+ years of experience leading QA for web, mobile, API and high-traffic digital
products. Strong background in test strategy, QA ownership, release readiness, risk-based testing, functional testing,
regression testing, smoke testing, exploratory testing, API testing, analytics validation, payment flows, subscription
systems, rewards logic, A/B testing and AI-powered product features.
AI is integrated into my daily QA workflow. I create and use AI agents to perform comprehensive website audits covering
functional flows, forms, APIs, SEO, GA4 and analytics tracking, accessibility, structured data, redirects, broken links,
assets, security headers, mobile behavior and content consistency.
I use Claude, ChatGPT and AI development tools to generate, review, debug and refactor tests, identify missing
coverage, analyze failures, create reusable QA workflows and prompts, and convert requirements or audit findings into
Jira tickets, test cases and Playwright automation tasks. I independently validate AI-generated results and combine
automation speed with strong product thinking and QA judgment.
