Freelance ASP.NET/C# developer

Hello, I'm Marcel, freelance ASP.NET/C# developer.

Since I was young, I've always been fond of computers and programming. I started with Basic on a simple home computer, and moved on to Visual Basic and later ASP when I got my own PC.

I learned ASP.NET/C# about 17 years ago, and I've been using that for the most since.

In freelance assignments, my main interest lies in back-end development. However, I'm also proficient in HTML5, CSS and JQuery for occasional front-end development.

I manage my own Windows Server with IIS and SQL Server.

Contact me via Linked-In to discuss if I can be of added value to your project.

Thank you!
Marcel
