During April 2026, contributed to the chatwoot/chatwoot repository by developing a targeted backend feature in Ruby on Rails to refine the notification flow for private notes. The work focused on preventing agents from receiving notifications when mentioning themselves, thereby reducing redundant alerts and streamlining the user experience. This was achieved by tightening the sender and recipient logic within the mentions service, ensuring that self-mentions no longer triggered unnecessary notifications. The implementation required no changes to the data schema, minimizing risk while enhancing reliability. The solution was delivered with clear traceability through associated pull requests and issue tracking, demonstrating careful backend development.
