Not integration. Not configuration. Engineering.
Anyone can wire an API to a chat box in an afternoon. Making it accurate, grounded, fast, safe, observable and cheap enough to run every day for a year is the actual discipline. That is the work.
Rate limiting, role-based access, input validation, signed webhooks, encrypted personal data and tested rollback paths. Every one of these is unglamorous, and every one of these is why the system is still standing in eighteen months.
Built on Cloudflare Workers, D1 and R2. No servers to patch, no region to be far from, no midnight capacity call. Speed as an architectural property rather than an optimisation project you fund in year two.
Not a junior with an AI assistant and a deadline, and not a prototype dressed up as a product. The essay on the three vibe coding traps sets out exactly what we are guarding against, and why.
Tell us the problem in plain language. We will tell you honestly whether it needs building, whether an existing tool would do the job, or whether the real answer is to stop doing that process altogether. Sometimes it is the third one.
What the system has to do, what it deliberately will not do, where the data lives and who is allowed to see it. Written down and agreed, so nobody discovers a disagreement in week six.
Access control, validation, encryption and audit logging go in as the features go in. Retrofitting them after a scare costs several times more and never fits as well.
A deployment you cannot reverse is a deployment you should not make. The path back gets tested, not assumed, and the same discipline applies to backups.
How it works, how to run it, what breaks it and what to do when it does. Being the only person who understands a system is good for a supplier and bad for a client, and we are not interested in that trade.
