I build and maintain end-to-end test automation with Playwright and TypeScript for the Certa Platform, using a PCOM layered design (Primitives→Components→Pages→Steps) to keep suites scalable and reliable.

I automate business workflows like form submissions, phone number validation, dashboard reports, and record management, collaborating through GitHub PRs with code review to protect architectural standards.

I design reusable test components and workflow definitions with SOLID principles and patterns like Builder and Facade, then wire in type-safe field bindings, multi-user scenarios, and Allure reporting.

Previously, I maintained a Selenium-based framework for MyPerfectResume, executed cross-browser/cross-platform UI testing, validated RESTful APIs with Postman and REST Assured, and improved CI/CD with Jenkins to accelerate regression cycles.
