Code Concise is a software design and development practice based in South Wales, UK. We build robust applications, modern web front ends and the systems behind them — drawing on nearly 30 years of software engineering across defence, commercial and interactive entertainment.
Defence
What we do
UI-heavy, performance-critical software in C# / .NET and C/C++, built to be stable and to stay responsive even when the work is heavy. Specialists in the Windows ecosystem and its UI frameworks.
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.
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
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.
Technologies
Flagship project
A Windows desktop application for viewing imagery, terrain and LIDAR in 2D and 3D, with APP-6 military symbols, overlays and orders of battle on top. Built in C# and WinUI 3, with a native C++ and Direct3D 12 renderer underneath.
3 videos · 3 explainers
A responsive, full-stack site for an independent automotive specialist, covering their services, booking enquiries and news. Bootstrap and JavaScript on the front, PHP and MySQL behind it.
Multiple contract engagements delivering software into secure, regulated defence environments — embedded interfaces, cryptographic key management, and technical ownership of a modern Windows planning and control application.
Building and evolving an in-house modelling and simulation capability (civil and defence) — distributed simulation, multi-system integration, and high-performance 2D and 3D visualisation.
Recommendations
Recommendations for Andy Eder, who runs the practice, written by colleagues and managers he has worked with. Published on LinkedIn (opens in a new tab).
I recruited Andy initially as a Software Engineer for the Modelling and Simulation team that I would later go on to lead… He has a rare mix of skills, in that he is an extremely able software engineer from a technical perspective, but also has a considerable artistic talent which comes through in his 3D and GUI work.
David Latheron
BLADE Architect, General Dynamics UK Limited
I found him to be proactive to the needs of the team, dedicated to the demands of the client and exhaustively hard working. His breadth of knowledge combined with a wealth of experience enables Andy to acquire new skills rapidly and adapt to the challenges of any new domain.
Tracy-Gregory Gilmore
Principal Frontend Software Engineer and Architect, CGI
I worked alongside Andy on a complex delivery (Approx. 200 Million GBP) for a major UK client… He is a good communicator at all levels of an organisation, and this makes him a strong team player. He is technically capable and is comfortable working on his own initiative in complex environments where requirements are sometimes very ambiguous.
