Worked on the cds-snc/notification-admin repository, focusing on backend improvements to the notification-admin dashboard. Addressed a Redis data validation bug by refining the logic to ensure the database is only queried when Redis lacks today’s data, rather than when it returns a dictionary of zero values. This update improved dashboard accuracy and reduced unnecessary database load, resulting in faster and more reliable user-facing metrics. Updated unit tests to align with the new validation approach, emphasizing robust testing practices. Utilized Python for backend development and API integration, demonstrating attention to data integrity and performance optimization within a production monitoring environment.
