Worked on enhancing reliability and internationalization for the twentyhq/twenty and virattt/dexter repositories, focusing on both user experience and integration stability. Addressed bugs in date and datetime pickers by refining Escape key handling and improving type safety in validation steps using TypeScript. Improved currency input components to respect locale-specific number formats, introducing utility functions and comprehensive tests. In the virattt/dexter project, expanded WhatsApp gateway utilities to normalize a wider range of phone number formats, backed by robust test coverage. Leveraged skills in React, JavaScript, and API integration to deliver solutions that reduce regressions and support international user requirements.
