About

Senior SDET / Acting Lead with experience in AI Quality Engineering, test automation, release strategy, and cross-functional integration testing. At Global Relay, I progressed from Junior SDET to Senior SDET / Acting Lead, working across Identity & Access Management and Artificial Intelligence product areas. I specialize in defining test strategy, improving release readiness, coordinating complex integration testing, mentoring engineers and testers, and building scalable testing practices for enterprise software. In my current AI role, I work with Python, Locust, Playwright, and Codex-driven automation to validate AI features across system, integration, regression, UAT, end-to-end, and non-deterministic behaviour scenarios. Highlights include reducing an AI release process from 3 weeks to 2 weeks, coordinating release planning and testing for 6 net-new AI services/features, conducting 20+ SDET technical interviews, guiding 2 manual testers, and leading test practices across multiple pods. ISTQB Certified Tester – Advanced Level, Test Manager. Interested in Senior SDET, QA Automation Lead, Quality Engineering Lead, and AI Quality Engineering opportunities.
