Developed a webhook delivery tracking capability for the e2b-dev/infra repository, focusing on improving observability and debugging of outbound webhooks. Designed and implemented a ClickHouse schema using both local and distributed tables with team-based sharding and a seven-day TTL retention policy. Leveraged SQL and database design skills to create migrations that established the new storage layer, capturing delivery status, timing, request and response metadata, and error details. This approach aligned with existing table patterns to ensure consistency and scalability, enabling teams to query delivery attempts efficiently, accelerate issue diagnosis, and support dashboards and SLA reporting for webhook workflows.
