I'm owning end-to-end QA for the Women’s Tennis Association’s multi-service API ecosystem, building Playwright and TypeScript automation, secure authentication coverage, and cross-service integration tests. I also extend AI-assisted workflows that turn JIRA and Confluence specifications into human-reviewed regression suites.

At Jiffy, I built a Playwright framework from scratch, increasing end-to-end coverage by an estimated 60% and reducing manual regression effort by 40%. At Xendit, my Gatling performance testing uncovered bottlenecks that contributed to a 25% improvement in p99 latency, while QA release gates reduced post-deployment hotfixes by 35%.

Over 11+ years, I've built QA functions from the ground up, automated web, mobile, API, and IoT platforms, and mentored automation engineers. I bring practical experience in quality strategy, risk-based testing, CI/CD workflows, and AI-enabled test generation.
