I build AI-assisted test automation, performance testing, and quality gates for logistics and travel platforms.
PhilippinesWhat I'm looking for
I've built test automation frameworks, performance test suites, and quality strategies for Quincus and CWT Philippines across logistics and travel platforms. Over 20 years in software testing, I've helped teams establish quality gates throughout the SDLC and keep production defect leakage below 10%.
At Quincus, I led 15–25 QA engineers and migrated automation from Robot Framework to Playwright + MCP for stronger AI integration. I introduced GitHub Copilot and Claude Code into daily test development, piloted AI-generated test cases and PR reviews, and achieved 90–100% in-sprint automation.
I build maintainable, modular frameworks covering web, REST APIs, Kafka event streams, mobile, and databases. I integrate tests into Jenkins and GitHub Actions, use WireMock and GreenMail for reliable coverage, and run JMeter performance testing with AWS, Grafana, and Kibana analysis.
I'm also developing a Playwright and TypeScript framework for a demo e-commerce application, including AI-powered CI review and failure triage in GitHub Actions. I enjoy mentoring QA engineers, setting coding standards, and turning test results into actionable production improvements.
