What we do

Engineering across the full product lifecycle

Nine service lines, grouped into the four kinds of problem clients actually arrive with.

All services

Product Engineering

Custom Software Development

Custom Software Development

Systems built around how your business actually works, rather than bent to fit a product that was designed for someone else's.

  • Architecture and data modelling before implementation
  • Integration with existing internal systems
  • Documentation and handover as work proceeds
Web Application Development

Web Application Development

Scalable web applications on modern frameworks — the surface most of our clients' users actually meet the product through.

  • React, Next.js, Angular and Vue front ends
  • Node.js, Python, Go, Java and .NET services
  • Performance work on first load and interaction
Mobile App Development

Mobile App Development

High-performance iOS and Android applications, built native or cross-platform depending on what the product genuinely needs.

  • Native iOS and Android, or React Native
  • Offline-tolerant data synchronisation
  • Store submission and release management
TV & Streaming Apps

TV & Streaming Apps

Applications for Roku, Fire TV and other smart TV platforms — a delivery surface most engineering teams have never shipped to.

  • Roku, Fire TV and smart TV platforms
  • Remote-first navigation and focus handling
  • Video delivery and playback performance

AI & Data

AI & Machine Learning

AI & Machine Learning

Applied AI that automates real work and supports decisions — built on the model providers and retrieval stacks already in production use.

  • OpenAI, Claude, Google and Meta model integration
  • Retrieval pipelines on Chroma, Milvus and MongoDB Atlas
  • LangChain and Hugging Face tooling
Data Analytics & Engineering

Data Analytics & Engineering

Turning operational data into something a team can act on — reporting that answers questions rather than producing more dashboards.

  • Data pipelines and warehouse modelling
  • Reporting and business intelligence surfaces
  • Event instrumentation and product analytics

Cloud & Platform

Cloud & DevOps

Cloud & DevOps

Migration, deployment and optimisation on AWS, Google Cloud and Azure — including the containerisation work that makes it maintainable afterwards.

  • AWS, Google Cloud and Azure
  • Docker and Kubernetes
  • Microservices, serverless and event-driven architectures
IoT & Connected Devices

IoT & Connected Devices

Connecting and managing physical devices, and making the data they produce usable by the rest of the business.

  • Device connectivity and fleet management
  • Telemetry ingestion and processing
  • Operational dashboards for connected estates

Design

Product Design & Discovery

Product Design & Discovery

Discovery, UX and interface design that resolves the expensive questions before implementation starts.

  • Discovery and interaction design
  • Interactive prototypes at the fidelity the question demands
  • Design systems handed over ready to implement

Industries

Software built for the way your sector works

Domain constraints differ more than technology does. Each of these has its own page covering how we approach software there.

What we build with

Chosen per engagement rather than by house preference — the constraint is what the system has to do, not what we already know.
