During February 2026, Matheus Avellar updated the email templates in the prefeitura-rio/pipelines_rj_sms repository to align with new S/CIT committee branding guidelines. He focused on backend development using Python, modifying template assets to incorporate the latest logo and footer text. The update was implemented through a targeted commit, ensuring that all outgoing email communications reflected the revised branding while minimizing rollout risk. No bugs were addressed during this period, and the work was limited to a single feature. The scope was narrow but required careful attention to template structure and asset integration to maintain consistency across communications.
