How engineers at Nextdoor use Codex to build without limits

Nextdoor engineers use Codex (an AI coding assistant) to shift from writing code step-by-step to focusing on desired outcomes, allowing individual engineers to build features end-to-end across multiple platforms rather than specializing in one system. This productivity boost has made engineering faster, so the main bottleneck is now deciding what to build strategically rather than how to build it. Codex also helps with debugging complex issues in systems like Rust databases and Kubernetes by persistently investigating problems and finding root causes.
