I’m a Senior QA Automation Engineer and SDET with 7+ years of experience building scalable test automation frameworks for enterprise applications in banking, e-commerce, and retail. I specialize in Playwright and TypeScript for end-to-end, API, and integration testing at scale, with a focus on measurable reductions in risk and time.

At M&T Bank (via UST), I built an end-to-end test automation suite of 250+ scenarios with Playwright and TypeScript, reducing regression cycle time from 4 days to under 6 hours. I automated REST API test coverage across 30+ banking microservices, identifying 40+ critical defects before production and improving service reliability by 35%, while integrating pipelines into GitLab CI for 100% execution on every merge request and cutting release approval time by 60%.

I also drive structural improvements and team alignment—introducing Page Object Model architecture reduced new test development time by 35% and lowered maintenance overhead across 3 parallel test environments. Partnering with backend, frontend, and DevOps squads, I implemented shift-left QA practices that reduced defect escape rate by 50% within the first 6 months.

Before that, at ZAMP (Burger King / Popeyes), I led QA automation for applications supporting 800+ stores across Brazil, including Cypress-based frontend E2E testing and Appium automation for iOS and Android. My performance and test planning work (JMeter/BlazeMeter, Azure Test Plans) and mentorship of junior QA engineers strengthened delivery quality, and my complementary Senior Frontend Developer background helps me test modern web experiences with more precision and empathy.
