During June 2025, Matt worked on the Learning-Mode-AI/Learning-Mode-AI repository, focusing on enhancing the reliability and maintainability of video processing within a browser extension. He refactored the video processing flow in JavaScript, centralizing processed-video checks in the sendVideoInfoToBackend function and removing dead code to streamline logic. By gating the 'processed' flag behind backend transcript verification, he addressed data inconsistencies and reduced the risk of videos being mis-marked as processed. This work improved data integrity and lowered maintenance overhead, demonstrating a thoughtful approach to front end development and backend integration using JavaScript and browser extension technologies.
