Stay up to date with practical insights on backend engineering, system design, and building reliable software.
APIs fail when they require interpretation instead of execution. The best APIs eliminate ambiguity through consistent design, predictable behavior, and self-evident contracts.
Read moreScattered environment variables and per-service property files work fine for one service. At ten services, they become an operational liability. Here is what a real configuration strategy looks like and why most teams implement it too late.
Read moreError responses are not secondary—they are the primary interface for debugging. Well-structured errors reduce support load, speed up integration, and make systems easier to operate.
Read moreMisusing HTTP status codes leads to broken retries, misleading metrics, and fragile clients. Treating them as part of your API contract improves reliability and reduces hidden complexity.
Read moreMicroservices trade one class of problem for several others. The architecture is legitimate — but teams routinely adopt it before they have the operational maturity to survive it.
