.NET Development

Nimblesite delivers .NET backend systems that are production-ready, well-tested, and maintainable. In 2026, API-first development, microservices architecture, and cloud-native deployment are standard expectations for enterprise backends. We build ASP.NET Core APIs, microservices, and event-driven systems designed to integrate with your existing Microsoft or Azure stack with no ramp-up time.

What You Get

APIs and Microservices

We build .NET backends designed to grow with your business. RESTful APIs, microservices architectures, and cloud-native services — well-documented, deployable to Azure, AWS, or GCP, and written so your team can own and extend them.

Automated Testing

Every .NET project includes comprehensive automated tests. We specialise in ASP.NET Core integration testing that runs in your CI/CD pipeline, catching regressions before they reach production. Your team ships updates with confidence.

CI/CD and DevOps

Automated build, test, and deployment pipelines are standard on every engagement. We configure your CI/CD for reliable, repeatable releases — whether you’re deploying to Azure, AWS, or Google Cloud.

Clean Architecture

We write code your team can maintain. Clean separation of concerns, consistent patterns, and practical documentation — not a codebase that requires the original developer to make changes.

Our .NET Tools

• Napper — our API testing tool using plain-text .nap files. Version-controlled, CI-friendly API tests with F# and C# scripting. We use it on every .NET project we deliver, and your team can adopt it to maintain test coverage independently.

Who This Is For

We work with established businesses that need reliable backend engineering. Whether you’re building a new API, modernising a legacy system, or integrating with Azure services, we deliver backends your team can own from day one.
