Jingying Han contributed to the sj-distributor/SmartTalk repository by enhancing backend reliability and scalability over a four-month period. She upgraded Hangfire background job processing to increase throughput, stabilized the audio pipeline by refactoring buffer management with C# and System.Buffers.ArrayPool, and improved memory efficiency for real-time audio streaming. Jingying also addressed time zone handling in monthly reporting, ensuring accurate UTC conversions for business metrics. Her work included implementing resilient API integrations with Twilio, adding asynchronous error handling, and introducing cache-based outage management. These efforts collectively improved system robustness, user experience, and operational visibility, demonstrating depth in backend and service integration engineering.
