About Me

Ronald Koopmans

I'm a passionate C# .NET developer who loves his job. I'm constantly looking for ways to improve myself on both personal and technical fronts, and trying to keep up with the latest in techniques and certifications.

Since my graduation in February 2011, I have been working with several .NET-based techniques like DotNetNuke, WPF, MVC and Sitecore. Focussing mainly on web development, I enjoy working with Sitecore most for it's endless possibilities and versatility.

To keep my knowledge up to date I've taken several Microsoft exams. This has resulted in being a Certified Ethical Hacker, Microsoft Certified Solutions Developer and a Sitecore Certified developer.

Having worked alone and in several (multi disciplined) scrum teams, I prefer working in teams because sharing knowledge leads to better products and new insights, and I feel that you can learn something new everyday, as long as you're surrounded with experts who are willing to learn.
