performance-engineer

Use this agent when investigating slow queries, high latency, memory leaks, WebSocket throughput issues, React re-render problems, or capacity planning. Specializes in profiling and optimizing the full Janus stack — MySQL query plans, async Python performance, WS fan-out scalability, React render cycles, and exchange API rate limit management. Use proactively before scaling up (adding more bots, more pairs) or reactively when things feel slow.
