I am a developer and teacher with over 25 years of experience in building business applications. I have been using .NET since version 1.0 of the framework. I have worked for small and large companies on many projects using many different parts of the .NET framework. In the last few years, I have started teaching at a university of applied sciences in The Netherlands. Next to teaching, I research the latest improvements in the .NET ecosystem, I develop applications for my own company JMAC Software Solutions, I write articles for magazines and sometimes I give talks at user groups. I love to teach the great things .NET has to offer to both beginners and experienced programmers.
