architecture

A 20-person team was running 14 microservices with three full-time engineers just keeping the infrastructure alive. We consolidated six of them into a modular monolith and cut their deploy time by 70%.

We ran load tests before a big product launch, got green across the board, and watched the system buckle under real traffic two days later. The tests weren't wrong — they just weren't testing reality.

A single slow database query triggered aggressive retries across four microservices. Within minutes, the entire order pipeline was down. Here's how we traced it and what we changed.

We added Redis to fix slow API responses. Instead we got stale data, thundering herds, and a system that was harder to debug than the original problem.
