PROFILE

Cristi Paval

Worked on the Expensify App and its forks, focusing on restoring and refining key user workflows and maintaining data integrity. Addressed complex UI and business logic issues, such as reinstating weekly transaction grouping and restoring delete functionality for card expenses, by applying targeted code reverts and precise refactoring. Enhanced telemetry integration and stabilized the user experience by re-enabling analytics and simplifying query construction. Used JavaScript, TypeScript, and React to deliver maintainable solutions in margelo/expensify-app-fork and callstack-internal/Expensify-App, demonstrating careful regression management and a disciplined approach to version control, test coverage, and policy compliance across front end and full stack development.
