HOW TO ENGAGE

The shape fits the work

Project — 3–6 months

Fixed-scope build of a discrete product, integration, or modernisation track. AI-paired delivery with weekly demos and a defined launch date.

Bounded scope, clear deliverables

Weekly demos

A launch date on the contract

Embedded Squad — 6–18 months

A senior squad plugged into your team, your tools, your standups. We bring AI-augmented velocity; you keep ownership of priorities.

Sustained delivery on your roadmap

Your rituals and tooling

You own the priorities

Retainer — open-ended

A small dedicated pod for ongoing evolution: feature drops, modernisation tickets, performance work, and a known SLA. Trade ad-hoc consultancy for a predictable line item.

Maintenance and evolution

On-call with a known SLA

WHAT WE BUILD

Six areas, one bar

AI Integration & Agents

Embed LLMs, RAG pipelines, and autonomous agents into your existing products. From spec to safety-tested rollout — including evals, guardrails, and observability.

Cloud-Native Modernisation

Lift legacy .NET, Java, or PHP monoliths into modern cloud-native architectures. Strangler-fig migrations that ship continuously, no big-bang rewrites.

Data Platforms & ML Ops

End-to-end data infra: ingestion, vector + relational stores, transformation pipelines, and model deployment with full observability.

Custom SaaS Engineering

Multi-tenant B2B products built right from week one — auth, billing, RBAC, audit, white-labelling — using patterns we've shipped 50+ times.

API & System Integration

Make systems talk: REST + GraphQL APIs, event-driven backbones, ETL between SaaS, ERP, and homegrown systems. Built to evolve, not to break.

Platform Engineering

Internal developer platforms: CI/CD, IaC, golden paths, observability, and dev portals — so your product engineers ship in days, not weeks.

HOW AI CHANGES DELIVERYAI-paired engineering, not AI-replacedEvery senior engineer on our squads pairs with an AI co-pilot codified with our 17-year pattern library. The output is reviewed, tested and owned by humans — but produced 2–3× faster than traditional pair programming.

Codified patterns, not promptsOur internal skills library encodes architecture, testing and review patterns we've refined for 17 years — applied automatically by the AI co-pilot.

Humans review every lineAI proposes, engineer disposes. Code review is a hard gate, with our own static analysis and security scans on top.

Your data stays yoursEnterprise endpoints with zero retention, or fully air-gapped on your tenancy when compliance demands it.

Same hourly rate, more outputWe don't charge a premium for AI velocity — the win goes back to you as compressed timelines or expanded scope.

THE PROCESS

How a build actually runs

01Discovery

Understand the system, the team, and the constraints — before scoping.

1–2 weeks

02Architecture

Define the technical north star and the path to get there incrementally.

1–2 weeks

03Build

AI-paired delivery with senior engineers. Weekly demos, continuous code review.

Most of the engagement

04Ship

Production rollout with monitoring, runbooks, and operational handover.

Rolling

05Sustain

Evolve the system through retainer — or hand off cleanly to your team.

Ongoing (optional)
