About

SDET with 3+ years building scalable test automation for fast-moving product teams. Currently the lead SDET at SalesMonk.ai — built the QA function from zero, a Playwright + TypeScript framework covering 50+ critical flows, and a CI/CD pipeline that ships daily with no manual gate.

Day-to-day work spans E2E testing, CI/CD integration, API & performance testing, and AI-assisted QA workflows. Web development on the side keeps me close to the products I'm testing.
