Worked on the Azure/azure-sdk-for-cpp repository to address a performance issue related to SSL socket writes. Focused on C++ development with an emphasis on multithreading and network programming, the work involved implementing a targeted fix that introduced a delay when curl_easy_send returned zero bytes. This approach prevented CPU busy-wait loops, allowing the thread scheduler to allocate resources more efficiently and improving throughput in IO-bound SSL scenarios. The solution maintained existing APIs and was carefully documented, demonstrating attention to code quality and clarity. The work showcased a strong understanding of performance-sensitive I/O paths and effective handling of concurrency challenges.
