AI Engineering

We do not “add AI”. We engineer systems that reason.

Aitina Tech's AI practice builds agentic systems that survive production: grounded in a real knowledge layer, measured against an evaluation set, fenced by guardrails, and running inside your own cloud account. The research behind it is published in full on The Software Lens.

The problem

The demo works. Production is a different discipline.

Almost every organisation now has an AI prototype that impressed a room. Very few have one in production carrying real load, real data and real accountability. The gap is not model quality — everyone has access to the same models. The gap is engineering: grounding, evaluation, guardrails, cost control, observability and a clear answer to “why did it do that?” when someone senior asks.

What usually goes wrong

Answers that are fluent and wrong. A retrieval layer nobody owns. Costs that scale with usage in a way no one modelled. No way to prove behaviour has not regressed since last month.

What we do instead

We treat an agent as a production system with a contract: defined inputs, a knowledge layer, an evaluation set, guardrails, a cost model, telemetry and an audit trail. Boring, and it is exactly what makes it shippable.

Where the research comes from

Our AIM and SaaC work — published in full on The Software Lens — is the architecture we build to. You can read the whole thing before you hire anybody.

How an engagement runs

From “we should do something with AI” to something that runs.

Short, checkpointed and cancellable. You are never more than a few weeks from the next honest decision point.

1

Frame

Two to three sessions. What decision or task is actually being automated, what does good look like, what is the cost of being wrong. Half the candidates get eliminated here, which saves you the budget.

2

Ground

Build the evaluation set and the knowledge layer before the clever part. If we cannot measure the answer, we do not build the agent.

3

Build

The system itself, in your cloud account, with guardrails, tracing and cost attribution from day one rather than retrofitted.

4

Operate

Regression runs on every change, drift monitoring, cost review and a documented audit trail. Handover to your team, or we run it.

Runs in your cloud, not ours

AWS Bedrock, Azure OpenAI or Google Vertex AI — inside your own account, your own VPC and your own data residency. We do not hold your data, and there is no platform of ours for you to be locked into. When the engagement ends, you own everything, including the evaluation sets.

Built for the questions auditors ask

Model and prompt versioning, retention and PII policy, human review points, decision logging and an evidence trail. If ISO 27001 or the EU AI Act is on your horizon, the controls belong in the architecture now rather than bolted on later.

Questions we get asked

Do we need our own data science team first?

No. Most of what makes an AI system work is software engineering — retrieval, contracts, evaluation, observability and cost control. We work alongside whatever team you have, and we deliberately hand over the evaluation sets and runbooks so your people can own it.

Which model should we use?

That is usually the least important decision, and it should stay reversible. We build behind a routing layer so models can be swapped as prices and capabilities change — which they do, constantly. Locking your architecture to one vendor's model is the mistake to avoid.

Will our data be used to train someone's model?

Not in the architectures we build. We run inside your own cloud account using enterprise model endpoints that do not train on your inputs, with data residency set explicitly. That boundary is written into the design, not assumed.

How do you know whether it is actually working?

An evaluation set built before the system, run on every change, with the results tracked over time. If a change makes answers worse, you find out in the pipeline rather than from a customer. This is the single biggest difference between a pilot and a product.

What if AI is the wrong answer for our problem?

Then we say so, and we would rather say it in the free hour than three months into a budget. A good deal of what gets pitched as AI is a reporting problem, a data-quality problem or a process problem wearing a costume.

Start here

One free hour. No pitch, no obligation.

Bring the problem you are stuck on — an integration that keeps breaking, a cloud bill nobody can explain, an AI project that is all demo and no product, or a platform you are about to invest in. You will leave with a straight answer and a written summary, whether or not you ever work with us.
