During a three-month period, Khoi Duong developed and enhanced backend features for the AtriaCoop/new-townhall-backend repository using Python, Django, and REST API principles. He built a post reaction system by introducing a Reaction model, updating serializers, and implementing a toggle endpoint with comprehensive validation and unit tests. He later refactored reaction handling into a dedicated service layer with a ReactionDao, improving data integrity and maintainability. Additionally, Khoi delivered chat group user removal functionality, enabling admins to manage group membership efficiently. His work emphasized code quality, database management, and robust backend patterns, supporting scalable feature development and reliable deployments.
March 2026 monthly summary for AtriaCoop/new-townhall-backend. This period focused on strengthening chat group user management and code quality.
