Worked on the Shopify/dalli repository to enhance the Dalli client’s resilience during network disruptions by addressing socket write and flush failures. Focused on Ruby-based error handling, the developer implemented logic to gracefully rescue IOError exceptions caused by closed streams, ensuring that data retrieval could continue even when connections were unexpectedly terminated. Integration testing was used to simulate closed socket scenarios, verifying the client’s stability and improving test coverage for network edge cases. This work strengthened runtime reliability and maintainability, demonstrating a test-driven approach and applying skills in network programming, integration testing, and robust error handling within a production Ruby environment.
