Worked on the actualbudget/actual repository to enhance the stability and reliability of the spending report feature. Focused on resolving a bug that previously caused saved date range selections to be lost when generating new reports, ensuring a smoother user experience. Applied TypeScript and front end development skills to implement the fix, accompanied by comprehensive unit and integration tests to validate date-range persistence. Documented the changes with clear release notes to support both users and support teams. Emphasized code quality and traceability by following best practices, improving CI readiness, and maintaining thorough test coverage throughout the development process.
