Worked on the AtriaCoop/new-townhall-backend repository, delivering four backend features over four months with a focus on user interaction and group management. Built a reaction system for posts, introducing a Reaction model and toggle endpoint, and later refactored reaction handling into a dedicated service layer with a ReactionDao for improved data integrity. Enhanced chat group administration by implementing user removal and addition through new DAO methods, supporting scalable group management. Addressed activity tracking reliability by resolving test flakiness using Django’s simple history. Emphasized code quality, maintainability, and robust unit testing throughout, leveraging Python, Django, and REST API development.

May 1, 2026May 2026 monthly summary for AtriaCoop/new-townhall-backend focused on delivering scalable Group Chat User Management and strengthening activity auditing. Key features delivered include enabling adding users to existing group chats via a new DAO method add_user, supported by a corresponding service and DAO for removing users, and comprehensive tests. Major bug fix addressed activity tracking reliability by resolving test flakiness when two objects were saved in the same millisecond, using Django's simple history prev_record to ensure accurate history records. These efforts improve collaboration workflows, test stability, and audit accuracy across the townhall backend.
