Every bug that reaches production is a tax on your revenue and reputation. I am a full-stack QA Lead who bridges the gap between user experience and engineering. If you are building in SaaS, AI/LLM, FinTech, Web, Mobile, or Connected-TV, I provide deep-dive testing across APIs, real devices, and complex integrations. Backed by 8+ years of Upwork QA leadership, I combine meticulous manual testing with automation to surface release risks before they hit production—and I document them with zero fluff.
