Sixteen Things That Break a Backend, and What Prevents Each
Backend engineering is taught as frameworks and turns out to be almost entirely about what happens when the database is slow, when the same request arrives twice, or when a downstream service stops answering without saying so. None of it is deep, all of it is invisible until it happens to you at an unpleasant hour. Sixteen situations and their usual answers.
Microservices Practices That Actually Keep Them Workable
Most microservices advice describes how to run them well and skips the decision that causes the most damage, which is splitting too early. The practices that matter once you genuinely need services: boundaries drawn around business capability, data ownership, failure handling, idempotency, events over synchronous calls, tracing and contract testing.
Five Kinds of API Test and When Each One Earns Its Place
Two engineers can both say the API is tested, both be telling the truth, and still disagree about whether it is ready. Functional, integration, regression, load and security testing, what each one catches, what each one structurally misses, how to spread your effort between them, and the one minute authorisation check that finds the most common serious API vulnerability.
Six Ways to Structure Work for an AI Agent
The word agent covers everything from a chatbot with one tool to a system that runs for twenty minutes deciding its own steps, and those do not fail the same way. Routing, parallelisation, orchestrator and workers, tool use, reflection and planning, what each is for, what goes wrong, and the durable execution work that separates a demo from something you can leave running.
What Actually Happens Between Your Pull Request and Production
Most engineers learn CI/CD as a sequence of buttons rather than a system, which works right up until the pipeline goes red and nobody knows which stage failed or why it matters. The five stages walked through one at a time, what each is protecting you from, why builds pin their versions, the difference between rolling, blue green and canary releases, and the ten second skill of reading a failed stage.
