The Systems Your Business Depends On
Web and mobile applications, APIs, data, cloud and DevOps, AI-powered products, integrations, and legacy systems.
Leadership, engineers, or an independent assessment
Most companies come to us needing one of three things. Each has a page of its own.
Fractional CTO
Senior technology leadership for strategy, architecture, engineering teams, vendors, and the technology decisions that shape your business.
Learn moreEngineering Team
Experienced engineers across frontend, backend, cloud, infrastructure, QA and AI, working inside your existing processes and architecture.
Learn moreTechnology Due Diligence
An independent technical assessment before an investment, an acquisition, or a major technology decision.
Learn moreThe systems businesses depend on
We build and modernize the technology systems businesses depend on. Follow any of these into the detail.
AI & Machine Learning
Ship AI features that survive production, from LLM integration and retrieval through to operating them reliably.
UI/UX Design
Product design with clear user flows, readable screens, and a system that keeps both consistent as the product grows.
Front-End Development
Build front ends designed for performance, accessibility, and the devices your customers actually use.
Back-End Development
Develop secure, scalable back ends, data layers, and infrastructure that stay reliable under load.
Mobile Development
Launch iOS and Android apps with fast starts, reliable sync, and a consistent experience on each platform.
QA Automation
Ship release-ready software with automated coverage of the journeys a failure would actually reach.
The technology itself is only part of the solution. We focus on building systems that are reliable, maintainable, secure, scalable, and cost-effective.
Across the full technology lifecycle
From application development and architecture to cloud infrastructure, databases, AI, DevOps, and production operations.
AI & Intelligent Systems
LLM integration, retrieval systems, AI workflow automation, and the infrastructure to run them reliably.
Application Engineering
Frontend, backend, and mobile development across the languages and frameworks a product actually needs.
Software Architecture
System design decisions that determine whether software stays maintainable as it grows.
Cloud & Infrastructure
Cloud architecture, infrastructure as code, and environments that are straightforward to operate.
Data & Databases
Relational and non-relational data, search, caching, and the performance work that goes with them.
Engineering & DevOps
Build and deployment automation, testing, monitoring, and the operational practices behind reliable delivery.
Modernization
Incremental modernisation of systems that work but are expensive, fragile, or difficult to change.
