During December 2025, Stefano Medini enhanced the ForestAdmin/agent-ruby repository by delivering RPC Schema Polling Enhancements for the Ruby integration. He replaced the existing Server-Sent Events approach with a robust polling mechanism for RPC datasource schema updates, introducing a configurable polling pool to efficiently manage multiple RPC clients. Leveraging Ruby and backend development skills, Stefano strengthened error handling and improved observability in schema fetch operations, which increased the system’s resilience and performance. His work addressed reliability and scalability challenges, particularly for multi-client deployments, and reduced operational incidents related to schema drift, demonstrating depth in API development and multithreading.
