Developed a Redis Stream-based data streaming solution for the dotnet/orleans repository, focusing on rewindable streams and checkpoint persistence to enhance reliability and recovery for end users. Leveraged C# and the Orleans framework to implement durable sequence tokens using Redis stream IDs, enabling robust end-to-end recovery and range-based reads. Refined Redis configuration and service wiring to support multi-package deployments, improving maintainability and operational stability. Expanded unit test coverage and strengthened CI workflows to ensure enterprise-grade streaming reliability. The work addressed fault tolerance and observability, delivering a recoverable streaming architecture that minimizes operational risk and supports stable, production-ready deployments.
