Worked on SalesforceCommerceCloud’s pwa-kit repository, focusing on front end reliability and release efficiency over a two-month period. Developed automated unit tests in JavaScript and TypeScript to validate user input handling in the Product View, ensuring invalid quantities reset to minimum values and reducing order errors. Enhanced product list filtering by verifying that disallowed refinements are excluded from user-facing options, aligning test coverage with business rules. Improved code quality through linting and formatting updates, and streamlined documentation and release workflows to accelerate shipping. Emphasized maintainable, readable test code in React, supporting easier onboarding and future refactoring for the team.
