About Frédéric

Do you have a web project that requires rigor, a business application, an internal tool, a custom site? I design robust solutions with the Microsoft stack (.NET, Blazor, RazorPages, ASP.NET).

What I do specifically:

  • Custom professional websites (RazorPages)
  • Business web applications and internal tools (Blazor, ASP.NET, NEXT.js)
  • Process automation and tool integration

What sets me apart: before coding, I seek to understand your real context.

My goal is not to deliver something complex, but something that really works, simple, robust, maintainable.

Available remotely or hybrid, based in Belgium (Huy region).
  • French

    Native or bilingual

  • English
