Worked on the vocdoni/ui-scaffold repository, delivering two targeted front end improvements using React and TypeScript. Developed a spreadsheet upload feature that trims whitespace from all cells during parsing, addressing data cleanliness and reducing import errors for users handling bulk data. Also simplified the user interface by removing SDK and Developer Portal links from the footer, streamlining navigation and supporting a smoother onboarding experience for developers. Both features were implemented with a focus on maintainability and immediate user impact, leveraging strong testing practices and attention to detail in front end development to enhance data integrity and overall usability of the application.
