What we do

Three things we do properly, rather than passably.

Desktop and native applications

UI-heavy, performance-critical software in C# / .NET and C/C++, multi-threaded to stay responsive however long it runs. Specialists in the Windows ecosystem and its UI frameworks.

Web applications and interfaces

Modern front ends built with the likes of TypeScript and React, RESTful APIs and clean client–server integration, on responsive layouts that hold up on any screen.

Visualisation, simulation and mapping

High-performance rendering and visualisation across modelling, simulation and synthetic environments, built on years in the games industry — plus bespoke GIS and mapping solutions in 2D and 3D space.

Where we work

Environments where getting it wrong is expensive.

Correctness, security, traceability and performance are expected as standard. We deliver to detailed specifications and evolving requirements, within the regulatory and security constraints that come with them.
