About me

Senior QA Engineer with 5+ years driving quality across SaaS platforms, API-heavy integrations, and production-critical workflows for remote US teams. I combine deep test strategy ownership with hands-on AI-assisted delivery, building and validating mobile/web products using Supabase, Firebase, Expo, and Flutter. I'm strongest in reducing release risk, improving defect detection early, and increasing delivery confidence through pragmatic automation, system-level testing, and cross-functional execution.
