About AI/ML Solutions & Integration

The gap between an AI demo and an AI system is enormous, and almost all of it is engineering. A prototype that impresses in a meeting has no evaluation harness, no cost ceiling, no handling for the request that returns nonsense, no audit trail for the decision it just influenced, and no plan for what happens when the underlying model is deprecated. Most stalled AI initiatives did not fail at the model — they failed at everything around it.

We start by pressure-testing the use case. Is there a measurable decision or task being improved? Is there a baseline to beat? What is the cost of a wrong answer, and who absorbs it? Several engagements have ended with us recommending a rules engine or a well-indexed search instead of a model, which is a cheaper and more honest outcome than shipping something that cannot be evaluated. When the case holds, we build: retrieval-augmented generation with chunking and reranking tuned against your corpus, agentic workflows with explicit tool boundaries and step limits, classical ML where tabular data and interpretability matter, or fine-tuning where a smaller specialised model beats a large general one on cost and latency.

Evaluation is non-negotiable. Every system ships with a golden dataset, automated regression evaluation in CI, and quality metrics tracked over time — because model behaviour drifts, prompts get edited, and providers change things underneath you. We add guardrails against prompt injection and data exfiltration, PII redaction before anything leaves your boundary, token cost budgets with alerting, graceful degradation when a provider is down, and human-in-the-loop review wherever the stakes justify it.

On the platform side we cover feature stores, model registries, versioned datasets, reproducible training pipelines and monitored inference endpoints — so a model in production is a governed artefact with lineage, not a pickle file someone copied to a server.

Why it matters

What you get

Honest use-case selection

We validate that a model beats a baseline and that the decision is measurable before writing code — and say so when a simpler approach wins.

Evaluation harnesses from day one

Golden datasets, automated regression evaluation in CI and drift tracking, so quality is measured rather than vibed.

Cost and latency under control

Model routing, caching, prompt compression and token budgets with alerting — because AI spend that nobody bounds tends not to stay bounded.

Security and privacy guardrails

Prompt injection defences, PII redaction at the boundary, tenant isolation and full audit logging of inputs, outputs and tool calls.

Provider independence

An abstraction layer across Anthropic, OpenAI, Google and open-weight models so you can switch on price, latency or capability without a rewrite.

How we deliver

Our process for this work

Adapted to this service specifically — not a generic five-box diagram.

  1. 01

    Opportunity assessment

    2–3 weeks

    Use-case scoring against value, data readiness and risk; baseline definition; and a written recommendation including the option of not using AI.

  2. 02

    Data readiness

    2–4 weeks

    Data quality profiling, labelling strategy where needed, corpus preparation, and the governance and consent position for the data involved.

  3. 03

    Prototype & evaluate

    3–6 weeks

    A working prototype measured against the baseline using a golden dataset, with cost per task and latency measured, not estimated.

  4. 04

    Productionise

    6–14 weeks

    Serving infrastructure, guardrails, observability, human review paths, CI evaluation gates and cost controls.

  5. 05

    Monitor & improve

    Ongoing

    Drift detection, quality regression alerts, prompt and retrieval iteration, and model upgrades evaluated before they are adopted.
