Custom Engineering
High-performance applications built to your architectural standards – not a reused playbook from another client's programme. AI agents assist the build; senior engineers govern every decision.
Software engineering consulting and legacy modernisation through AI-augmented engineering pipelines. Secure, high-performance applications governed against a technical roadmap built for your specific outcome.
Engineering without architectural governance is expensive rework. Our software consultancy delivers full-stack engineering, microservices, and legacy software modernisation against a technical roadmap built for your specific outcome – with AI-augmented engineering pipelines covering code review, test generation, and refactoring. The result: roadmap-to-production timelines compress without quality dropping.
Five capability areas, each governed by senior Software practitioners and tied to a clear business outcome. No capability exists for its own sake – each one serves your programme's specific objective.
High-performance applications built to your architectural standards – not a reused playbook from another client's programme. AI agents assist the build; senior engineers govern every decision.
Scalable, modular architectures designed for interoperability, resilience, and the ability to evolve without a full rewrite when the product roadmap shifts.
AI-assisted code generation, code review, test creation, and refactoring sit inside CI/CD by default – compressing timelines and lifting baseline quality, not replacing engineers.
OWASP-grade security and load-tested performance engineered in from the start – not audited in after go-live. AI-assisted SAST and dependency scanning catch issues before they merge.
Cloud-native and serverless architectures that reduce operational overhead and scale without engineering intervention – ready for AI-driven traffic shapes you can't always predict.
A selection of software programmes our clients have entrusted to us – from platform re-engineering to enterprise-scale application development.
A selection of the senior Software practitioners who lead and deliver our client engagements. The people you meet in the discovery are the people who deliver.

Common questions we get from senior technology leaders evaluating this work. Direct answers, no hedging. Open one to read in full.
AI agents embedded across the engineering pipeline – assisted code generation, automated test scaffolding, code review at PR time, refactoring proposals for legacy modernisation. Senior engineers make the architectural and design decisions. The AI handles the repetitive translation and validation work that used to slow delivery down. Faster output on a higher quality baseline.
Governance lives in the pipeline. Architectural decision records for every significant call. Automated checks against the agreed architecture as part of CI. And senior practitioners with explicit authority to slow things down when a shortcut would create permanent debt that takes years to repay. Speed comes from clearing the right obstacles out of the way – never from skipping the obstacles that matter.
Yes. The rescue starts with a clear-eyed assessment – code health, team capability, process maturity, stakeholder alignment, the works. Then a sequenced recovery plan. Stabilise. Rebuild the foundations. Resume delivery on a defensible cadence. Our published case study on rescuing a failing cost-optimisation platform documents the pattern in detail, including the parts that hurt.
Programme delivery is the default. Senior-led, outcome-aligned engagements are where this model creates the most value. We do place senior individuals into client teams when the engagement specifically calls for it. We won’t compete with body-shop pricing on junior contractors. The model is built around senior practitioners shaping outcomes, never headcount on a rate card.
Strangler pattern. New services run alongside the legacy system. Capabilities move across one module at a time. The old system retires in stages as traffic shifts onto the new estate. AI-assisted code translation accelerates the discovery and refactoring phases. Rip-and-replace earns its place only when the legacy system is genuinely unsalvageable, which is rarer than the proposal deck usually claims.
Four areas, one standard. Each specialism is led by senior practitioners with deep domain expertise – explore the others.
Most AI deployments are performance theatre. Our generative AI consulting practice integrates AI – from workflow automation and intelligent decision-making to custom LLMs and agentic systems – where it demonstrably pays back, and we'll tell you directly when it won't.

Explore Cloud ConsultancyMost organisations have more data than they can act on. We build AI-ready data platforms, AI-augmented pipelines, and production ML foundations that close the gap between data collected and decisions made – with governance and lineage architected in from the start.
