Let AI Agents Rewrite a 92M-Message-a-Day Node Service to Go
Our Results Daemon processes about 92 million messages a day. We recently rewrote it from Node.js to Go, and we let Claude Code write it.We wanted to know whether we could trust an agentic rewrite for a critical, high-throughput production service rather than a prototype. It shipped with zero incidents, a 70% reduction in running pods, and a lighter database load.

Our Results Daemon processes about 92 million messages a day. We recently rewrote it from Node.js to Go, and we let Claude Code write it.We wanted to know whether we could trust an agentic rewrite for a critical, high-throughput production service rather than a prototype. It shipped with zero incidents, a 70% reduction in running pods, and a lighter database load. Go's stronger type system also proved a better fit for agents than JavaScript, adding protection against regressions and letting us ship faster and with more confidence.What made it work was the test harness we built before the agent wrote a line.
