Worked on the microsoft/garnet repository to optimize performance in size parsing utilities by refactoring ParseSize and PrettySize methods. The update replaced char[] with ReadOnlySpan<char> in C#, reducing temporary memory allocations and improving throughput without altering functional behavior or public APIs. Focused on code refactoring and performance optimization, the work targeted hot-path utility methods to enhance memory efficiency and reduce garbage collection pressure. No bugs were addressed during this period, as the effort centered on strengthening Garnet’s parsing performance. The approach maintained compatibility and outlined further opportunities for memory management improvements, demonstrating attention to both detail and maintainability.
