Open Source Contributions
Contributing to the developer community through open source projects
GitHub duplication Fixed and Migration
Fixed a critical issue in the user authentication system where changing GitHub usernames led to duplicate document creation. Implemented a robust migration strategy to handle username updates by maintaining a single source of truth and updating all related references. This enhancement improved data consistency and prevented potential authentication conflicts.
