I’m a Senior Quality Engineer with over ten years of experience in test development and quality assurance, specializing in web functional and automated testing. I build Cypress and Playwright automation frameworks from scratch, including robust project structure, configuration, utility functions, and plugin integration. I also leverage Jenkins integration to keep automation reliable and fast.

At Red Hat (June 2015–Present), I developed a Cypress web automation framework from scratch, including element layer encapsulation, custom commands, failure screenshot/recording, and JUnit reporting. I led evaluation and migration from Cypress to Playwright Automation CI/CD, and built Jenkins Pipeline scripts for continuous integration with scheduled and manual triggers—improving iteration efficiency by over 40%. I also work with Prow (K8s CI framework) to write Step definitions and configs that link test repos and support customized automation for code changes.

My work covers full-cycle web module testing, including functional, regression, compatibility, and UXD testing. I’ve conducted web security testing (password masking, unauthorized access control, API privilege checks, and sensitive information leakage prevention) and validated PatternFly component upgrades to prevent rendering and interaction issues. I practice Shift-Left Testing in Agile/Scrum by participating early in requirement reviews and automation/script reviews, and I mentor my team through technical sharing to strengthen overall delivery quality.
