Stay up to date with practical insights on backend engineering, system design, and building reliable software.
Once an API has real consumers, every change becomes a contract risk. Versioning is the only reliable way to evolve safely without breaking production systems.
Read moreAPIs are often treated as simple CRUD endpoints, but real-world systems are more tangled. Domain-driven architecture (DDA) helps keep complexity under control.
Read moreBackground job queues and cron jobs solve different scheduling problems — and the common mistake of using cron for everything eventually produces a fragile task scheduler that you will spend three months replacing.
Read moreBug detection is a side effect of good code review, not the goal. The primary value of review is distributing knowledge about how the system works and why decisions were made — a goal that requires a different approach.
Read moreInconsistent error shapes across endpoints force developers to write defensive code for every route they touch. Consistency is not polish — it is correctness.
