Worked on the Learning-Mode-AI/Learning-Mode-AI repository to enhance the reliability and maintainability of video processing within a browser extension. Focused on front end development using JavaScript, the work involved refactoring the video processing flow to ensure that videos are marked as processed only after backend verification of transcripts. Centralized the processed-video checks within the sendVideoInfoToBackend function and removed dead code, which reduced data inconsistencies and simplified future maintenance. By cleaning up unused routes and streamlining logic, the changes improved data integrity, lowered the risk of mis-marked videos, and established a clearer, more maintainable foundation for future enhancements.
