Worked on the pennlabs/penn-mobile repository to enhance notification delivery and database schema reliability. Developed an immediate notification delivery system by replacing the previous Celery-based asynchronous dispatch with direct sending, which reduced system overhead and improved notification latency for end users. Addressed potential data truncation issues by increasing the template_path field length from 50 to 200 characters in the Page model, implementing a corresponding database migration to ensure data integrity. Utilized Python and Django for backend development, API integration, and database migrations, focusing on maintainability and performance improvements within the codebase during the month-long contribution period.
