What I'm looking for

I’m looking to own QA strategy end-to-end—building resilient Cypress/Selenium automation, using AI for coverage and defect triage, and embedding quality gates in CI/CD while mentoring engineers to deliver fast, reliable releases.

I’m a Senior QA Engineer with 7+ years of dedicated QA experience and 8+ years in tech overall, specializing in building automation frameworks that actually stick. I thrive at the intersection of quality, speed, and reliability, and I bring a UI/UX design background that helps me spot usability issues other QAs miss.

At Kora, I lead QA operations across web and mobile products—owning test strategy, automation architecture, and release quality standards across multiple concurrent workstreams. I design and maintain Cypress automation frameworks for functional, regression, and integration testing, and I use AI agents to generate, review, and iterate on test cases to accelerate coverage.

I’ve driven measurable outcomes at Reliance Health by reducing regression testing time by 76% through end-to-end Cypress automation scripts, and by driving production bug rates down by 99% via systematic test planning. I also integrated AI-powered coverage gap analysis that scans the app and automation suite and outputs structured gap reports to Google Sheets—giving continuous visibility into QA completeness.

Beyond execution, I mentor junior QA engineers to develop stronger testing instincts and adopt modern tooling, including AI into their day-to-day workflow. With growing cybersecurity knowledge (OWASP), I think about attack surfaces—not just happy paths—while maintaining high standards for clear, actionable bug reporting in Jira.
