ASP.NET Core APIs
Minimal APIs and controllers with Entity Framework Core, FluentValidation and clear dependency injection.
Languages and frameworks
C# development.
C# is a modern, strongly typed language with excellent tooling, used for enterprise back ends and as the scripting language of Unity. We reach for it when type safety, long-term maintainability or the Microsoft ecosystem matters.
A short call. Your first build, a fixed quote, and the timeline. No obligation.
What we build with C#
Where it fits.
Unity gameplay code
Gameplay systems, editor tools and ScriptableObject-driven data in Unity projects.
Background services
Worker services and queue consumers that run as hosted services, with Polly for retry and resilience policies.
Windows tools
Desktop utilities and integrations built with WPF or WinForms for teams that still run on Windows.
When it is the right choice
Choose C# when
- →You are building on Azure or inside a Microsoft-heavy environment.
- →You are making a Unity game.
- →You want a typed language with first-class async and good IDE support.
Worth knowing
Honest trade-offs.
- →Cross-platform support is strong on modern .NET, but older .NET Framework projects remain Windows-bound.
- →Hiring and tooling are great in enterprise circles, but the open-source library scene for AI work is smaller than Python's.

Common questions
Before you start.
Can C# services run on Linux?
Yes. Modern .NET runs on Linux and in containers, which is how we usually deploy it.
Is C# a good choice for AI features?
It works well for calling model APIs and orchestrating them, and Azure SDKs are mature. For training and heavy data science we use Python alongside it.
Can you take over an existing C# codebase?
Yes. We start with a review of structure, tests and dependencies, then agree a plan to stabilise and extend it.
What do you build with C#?
Enterprise back ends, Unity games, Windows tooling, APIs, and related work. We choose C# when it is the right fit for the product, the team and the budget.
Can you work with our existing C# code?
Yes. We can review what you have, fix what is fragile, and extend it, or build alongside your team.
