AI & intelligent services

The engineering that turns a working model into a system people rely on.

Custom AI applications, integration into the landscape you already run, and deployment into an environment your security team will sign off — cloud, private cloud, on-premises, hybrid or sovereign.

01 — Where prototypes die

The model was never the hard part.
Everything around it is.

A prototype needs a model and a demo dataset. A system needs identity, entitlements, integration, error handling, observability, cost control, versioning, rollback and a deployment path your security review will accept.

That is ordinary — if unglamorous — software engineering, and it is where most enterprise AI effort actually goes. We treat AI systems as production software from the first commit rather than promoting a notebook and hoping.

Because our teams build on the same foundations across engagements, the parts that are identical every time — connectors, retrieval, orchestration, guardrails, audit — are reused rather than rewritten, and the budget goes to what is specific to you.

02 — What we build

Applications, services and the plumbing between them.

PRODUCTION SOFTWARE THAT HAPPENS TO USE AI.

03 — What the work covers

Six engineering disciplines under one team.

Non-functionals we design for

Identity, single sign-on and entitlements

Latency and throughput budgets

Cost per request and per tenant

Failure, retry and degradation behaviour

Observability, tracing and alerting

Data residency and retention

Custom AI applications

Full-stack products around an AI capability — the interface, the workflow, the permissions and the administration, not just an endpoint.

Enterprise integration

Connectors and services against ERP, CRM, EAM, ITSM, HR and data platforms, with authentication, retry and reconciliation handled properly.

LLM engineering

Prompt and context architecture, structured output, tool schemas, routing between models, caching and cost control — versioned and tested like any other code.

Model engineering

Classical machine learning, vision and forecasting where they beat a language model, including training, tuning and the pipelines behind them.

MLOps and LLMOps

CI/CD for models, prompts and datasets; environment promotion; evaluation gates inside the pipeline; and rollback that actually works.

Deployment and hardening

Cloud, private cloud, on-premises, hybrid or sovereign, with secrets management, network posture, logging and the evidence a security review will ask for.

04 — What ships with the system

Six things handed over alongside the code.

A system your own engineers cannot run, review or replace is not finished, however well it demonstrates.

01

A deployment path

Infrastructure as code, environments and a promotion route, from day one rather than at the end.

02

An evaluation gate

Quality checks run in the pipeline, and a regression blocks the release.

03

Observability

Traces, metrics, cost and quality visible to whoever runs it.

04

Documentation

Architecture, runbooks and handover material written for your engineers.

05

A security package

The artefacts your review needs — data flows, controls, dependencies and threat notes.

06

An exit route

No lock-in by accident: your code, your data, your infrastructure.

05 — How the build runs

Increments you can see, from the second week.

Two-week increments against a working system, so the direction is correctable while correcting it is still cheap.

011–2 weeks

Architect

Solution and data architecture, non-functionals, and the deployment target.

022-week increments

Build

Working software each increment, reviewed against real data.

03In parallel

Integrate

Enterprise systems, identity and data flows, tested end to end.

043–4 weeks

Harden

Security, performance, cost, failure behaviour and the evidence pack.

05Go-live

Deploy

Release into your environment, with handover and runbooks.

06 — How it fits

Your landscape, with AI services inside it.

INTEGRATED, NOT ADJACENT.

07 — Sound familiar?

Where engineering work gets called in.

Our proof of concept cannot pass a security review.

Hardening & deployment

It works on sample data and falls over on ours.

Data & integration engineering

This has to run inside our own network.

On-premises deployment

Nobody can tell us what it will cost per month.

Cost engineering

Every AI project here rebuilds the same connectors.

Platform foundations

We want our own team to own it afterwards.

Build and hand over

Have a problem worth solving?

Bring us the prototype that cannot ship.

Most of them are closer than they look. We will tell you what stands between it and production, and what that actually costs.
