Professional

A quality engineering leader with over 15 years of experience turning quality chaos into structured, automated confidence. Embedded in product teams end-to-end — from shaping requirements and test strategy to building CI-integrated automation frameworks and leading QA chapters. A strong outsourcing background enables fast context-switching across domains: fintech, networking, streaming, IoT, e-commerce. In 2024–25, AI-augmented testing became a core part of the toolkit — leveraging GitHub Copilot, Claude Code, and agentic workflows to accelerate test creation, reduce manual regression effort, and surface edge cases earlier in the cycle.
