PROFILE

Zikun Zhu

Over a three-month period, contributed to the alibaba/loongsuite-go-agent repository by building advanced observability and cost management features for Ollama API integrations. Developed OpenTelemetry instrumentation for Chat and Generate APIs, capturing detailed metrics such as model names, operation types, and token counts to support data-driven optimization of LLM workloads. Introduced streaming support with real-time metrics like Time To First Token and throughput, enhancing responsiveness and monitoring capabilities. Delivered a thread-safe cost calculation engine with configurable pricing and SRE-style budget tracking, including anomaly detection. All features were implemented in Go, with comprehensive testing and documentation to ensure reliability and maintainability.
