I work as a freelance Senior .NET Developer, specializing in:

  • AI integration : integrating AI into existing .NET applications with Semantic Kernel and OpenAI/Azure AI
  • Identity & SSO : OAuth2, OpenID Connect, SCIM, Azure Entra ID, IdentityServer4 and OpenIddict. Multiple secure token services built.
  • Backend development : APIs, services and integrations in C# and .NET
  • Azure Cloud & DevOps : infrastructure, deployment, CI/CD pipelines

I prefer working in teams where I can handle the full process: from design to production.

I'm available 2 days per week. Full-time is not an option as I spend the other days building my own platforms (Invullen.nl, Factuur-Assist.nl). I learn a lot from that, and I bring that experience into client work.

We agree on fixed days, planned at least 4 weeks ahead. For shorter tasks or individual days, I can be scheduled 2-3 weeks in advance.

Both. I'm based in the Utrecht region (Netherlands) and available for on-site and remote work.

For on-site work I calculate a maximum travel time of 1 hour (including average traffic delays).

Get in touch for a rate that fits the project. I work on an hourly rate or fixed price per project, depending on scope.

My primary stack:

  • AI: Claude Code, Semantic Kernel, OpenAI, Azure AI Foundry
  • Identity: OAuth2, OpenID Connect, Azure Entra ID, SCIM, IdentityServer4, OpenIddict
  • .NET & Cloud: .NET 10, C#, Azure, Docker, Kubernetes (AKS), SQL Server
  • Frontend: Vue 2/3, Angular, TypeScript
  • DevOps: Azure DevOps, CI/CD, Playwright

We start with an introductory meeting to discuss the project. Then we make concrete agreements about scope, planning and rate.

I prefer working in short iterations: deliver something quickly, process feedback, move forward. This way you see results fast and we keep the direction sharp.

I work on the basis of the Model ICT Agreement (Dutch standard).

Yes. I have professional liability insurance from Hiscox in the name of Software Assist BV.
