" summary

Describes building and testing custom Nginx modules in C compiled into the binary for ad-serving at scale, claiming a production cluster handles 1.75 million req/s across 12 Nginx instances. Uses a Scala-based test harness to spawn Nginx and mock upstreams, runs 20-hour stress tests to catch leaks, debugs with gdb and core dumps, and records percentiles with HDR Histogram. Shows a load‑balancer module, health checks and default-response fallback that work in production.
