PROFILE
Zhangjianning.zjn
Worked on backend development and performance optimization for the alibaba/rtp-llm repository, focusing on stabilizing streaming beam search and improving API reliability. Addressed critical bugs in C++ and Python, such as fixing stream termination logic and restoring reliable API server startup, which reduced latency and prevented resource leaks. Enhanced text generation correctness by refining stop words handling and improved observability through more accurate metrics reporting for TTFT and TPOT. Delivered targeted performance improvements by tuning Python garbage collection, lowering runtime overhead. Demonstrated strong debugging, unit testing, and resource management skills while prioritizing production stability and maintainability in latency-sensitive environments.
