Stay up to date with practical insights on backend engineering, system design, and building reliable software.
Passing CI is a necessary condition for a safe deployment — not a sufficient one. The gap between green tests and production reliability is filled with environment differences, data assumptions, and integration behaviors your test suite was never designed to catch.
