AI Engineering

From pilot to production. Most AI pilots never ship. We build the parts that make them production systems: retrieval that is correct, agents that are bounded, evaluation that catches regressions, and privacy that survives an audit.

Talk about AI Engineering

Problems we solve.

  • A pilot that impressed the board but cannot be trusted with real customers.
  • Answers that are fluent and wrong, with no way to measure how often.
  • Data that cannot leave the country, the building or the device.
  • Cost per query that grows faster than usage.
  • A model bolted onto a .NET or JavaScript system nobody wants to touch.
  • No one on the team who has taken an AI feature to production.

What we deliver.

Packages with a defined scope and a typical duration. Each ends with something you keep.

2 to 3 weeks

AI readiness review

Where AI pays off in your systems, what data you have, what it will cost to run, and a sequenced plan.

6 to 12 weeks

LLM feature build

Retrieval, agents and tool use integrated into your existing product, with guardrails and observability.

4 to 10 weeks

On-device and private AI

Models that run on the phone, on your servers or in your EU region, with no data leaving your control.

3 to 4 weeks

Evaluation and safety harness

Golden sets, automated grading and release gates so quality is measured, not assumed.

Retrieval and guardrails sit between your data and the model, so every answer can be traced, graded and switched to a different model without touching the product.
