Worked on the NethermindEth/nethermind repository to enhance streaming stability and reliability in JSON-RPC and IPC workflows. Addressed a bug in the CountingStreamPipeWriter by refactoring the flush logic, moving threshold-driven flushes to the buffer allocation phase to prevent premature buffer invalidation and ArgumentOutOfRangeException during JSON serialization. Leveraged C#, System.IO.Pipelines, and unit testing to ensure buffer integrity and maintain bounded memory usage. Developed a dedicated test suite covering both synchronous and asynchronous serialization paths, improving overall robustness. Collaborated with co-authors to document and codify these changes, supporting maintainability and knowledge sharing within the codebase.
