AI Feature Integration

One production-ready feature, not a science experiment.

Price · ex. VAT €890
Duration 10 to 14 working days
Booked via Stripe · written brief

We build one AI feature at a time, scoped and shipped like any other feature. The deliverable is not a prototype — it is a feature with prompt versioning, an evaluation harness, cost monitoring per call, and a working fallback for when the model is rate-limited or down. We do not bolt AI onto a product just to be able to say AI is in the product. We will tell you honestly when a feature does not need a model behind it.

Deliverables

What ships.

Standard list for this chapter. Adjusted per brief when the engagement warrants it.

01 One scoped AI feature, integrated into your existing product.
02 Prompts versioned and reviewable like any other source code.
03 An evaluation harness with a small but curated test set.
04 Cost monitoring per call, with alarms and budget caps.
05 Working fallback behaviour when the model is unavailable.
06 Documentation for the team that owns it after we leave.
Phases

How it runs.

Same shape every time. Skipping a phase is rare and always written down.

01 — Scoping

We argue the feature down to one specific, measurable outcome.

02 — Prototype

A two-day spike to confirm the approach is even possible at the quality bar.

03 — Production

Real integration, with versioned prompts, evals, costs, and fallbacks.

04 — Hardening

Edge cases, retries, observability, abuse handling.

05 — Handover

Documentation, training, and an explicit list of what to monitor.
