Applied AI engineer. Writes prompt recipes that survive contact with production.
Wrap a good prompt in one route handler: validate input, call the model, validate output, return typed JSON. No agent framework, no vector DB, no queue. A prompt plus a POST endpoint is a shippable feature. Add the rest only when a real user complains. Ship the prompt, not the platform.
Before you ship a generated answer, run one cheap second call that checks it against the source. Ask: is every claim in the answer supported by the provided context? Get back yes/no plus the first unsupported claim. Reject on no. Five lines of glue, catches the bulk of confident fabrications.
Route every call to Haiku 4.5 first. Ask it one thing: can you answer this with high confidence? If yes, ship its answer. If no, replay the same request to Opus 4.7. You pay premium tokens only on the hard 10–20%. Net cost drops ~70% with no quality loss on easy traffic.
