AI & Machine Learning
AI strategy, use-case selection and data readiness, then custom machine learning models for NLP, forecasting and prediction.
We design, build and operate AI systems that move beyond demos. Bring 25+ years of engineering experience to your hardest AI problem — for teams across the US, the UK and Europe — with standards shaped by work for Mozilla, Walmart, Porsche and Fortune 500 organisations.
From strategy and data to evaluation and operation, we build the parts that turn an AI idea into a dependable system.
AI strategy, use-case selection and data readiness, then custom machine learning models for NLP, forecasting and prediction.
Production LLM applications, RAG, evaluation and model integration grounded in your data and operating constraints.
Controlled AI agents and deterministic workflows that automate high-value work with clear human oversight.
Vision systems for image and video detection, OCR and document vision, and visual inspection, deployed to the cloud or at the edge.
The architecture, deployment, monitoring, cost controls and governance required to keep production AI dependable.
We combine AI strategy with the engineering discipline required to make it work in production. No theatre, no generic roadmap and no model choice without evidence.
25+ years of engineering experience applied to production AI decisions.
Validate the highest-risk assumptions early, then invest in what survives real evaluation.
Clear technical decisions, direct answers and visible progress throughout the engagement.
Evaluation, monitoring, guardrails and cost controls are designed in from the start.
Accuracy, latency, operating cost and business value are made explicit before launch.
Your organisation retains the code, documentation and knowledge needed to own the system.
A proven methodology refined over hundreds of successful projects.
A free 30-minute call where we talk through your goals and constraints, followed by a scoped proposal.
We test the approach against representative data and define the evaluation needed to justify production investment.
The validated system is integrated, deployed and instrumented for reliable production use.
We monitor quality, drift, latency and cost, then improve the system using production evidence.
