Worked on enhancing TrendRadar by developing an AI-driven notification system that delivers incremental alerts for newly added items, aiming to reduce notification noise and improve user engagement. The implementation involved backend development using Python, focusing on AI integration to ensure only relevant updates trigger notifications. Changes were committed to the sansan0/TrendRadar repository, including a targeted fix for incremental notifications and the removal of outdated tests to maintain alignment with the updated logic. The work demonstrated careful attention to maintainability and user value, with clear documentation and traceable commit history supporting collaborative development and reliable feature delivery within the project.
