Worked on the margelo/expensify-app-fork repository, focusing on front end performance and code quality improvements using React and TypeScript. Delivered optimizations for policy ID selection by refactoring retrieval logic, removing deep-equality selectors, and leveraging useMemo to reduce unnecessary renders. Enhanced archived reports ID set computation by memoizing filter logic and simplifying the approach to compute IDs directly, then reverted this memoization after identifying performance regressions, prioritizing stability. Additionally, improved code maintainability through Prettier-based formatting and removal of redundant imports. Demonstrated skills in custom hooks, state management, and performance optimization, resulting in a more responsive and maintainable codebase.
