Stay up to date with practical insights on backend engineering, system design, and building reliable software.
The gap between what was asked for and what was needed is responsible for more wasted engineering effort than any technical failure. Closing that gap is an engineering responsibility, not a product management one.
Read moreTeams that treat rollback as an admission of failure avoid building rollback capability — which means when a bad deployment happens, recovery takes far longer than it should. A defined, tested rollback path is a prerequisite for confident deployment.
Read moreUnstructured logs are difficult to query and impossible to alert on reliably. Structured logging with consistent correlation IDs and the right log levels transforms logs from a last resort into a first-line diagnostic tool.
Read moreDenormalized schemas feel convenient until you have update anomalies, redundant data across millions of rows, and queries that require self-joins to answer basic questions — normalization is not academic overhead, it is how you maintain data integrity at scale.
Read moreUnconfigured or incorrectly configured timeouts are one of the most common root causes of cascading failures in microservices. Default HTTP client timeouts are designed for general-purpose use, not for production inter-service communication.
