Worked on enhancing large data export capabilities in the apache/arrow-dotnet and mathworks/arrow repositories by addressing a 2GB memory limitation in Record Batch exports. Upgraded the ExportedAllocationOwner component’s memory tracking from 32-bit to 64-bit integers, eliminating integer overflow risks and enabling support for larger data sets in analytics workflows. Applied consistent bug fixes and introduced new tests to ensure reliability and overflow handling across both repositories. Demonstrated expertise in C# development, memory management, and data export processes, with a disciplined approach to cross-repository maintenance and test coverage that improved the robustness of production data pipelines.
