Over a two-month period, contributed backend engineering work to the getsentry/sentry repository, focusing on reliability and maintainability. Developed a Redis-backed deduplication mechanism for GitHub webhook events, leveraging Python and Redis to ensure idempotent processing by caching delivery IDs with a short time-to-live. This approach reduced duplicate event handling and improved consistency during high-traffic periods. In addition, performed codebase cleanup using Django, removing obsolete tables and applications to streamline the code and reduce technical debt. The work emphasized robust API integration, efficient resource utilization, and safer deployments, resulting in a leaner backend architecture that supports future feature development.
