Worked on the Adyen/adyen-web repository, delivering seven features and resolving three bugs over five months with a focus on payment UI, session handling, and developer tooling. Built reusable components such as CopyButton, enhanced payment flows like UPI Autopay, and improved responsive design for mobile checkout. Applied JavaScript, TypeScript, and SCSS to refactor components, manage dependencies, and streamline event handling. Improved test reliability by stabilizing mocks and expanding test coverage. Enhanced documentation and process governance with updated PR templates and release notes, supporting maintainability and onboarding. Prioritized user experience, code consistency, and integration reliability across payment methods and device types.
