Since early 2001 I've been working full time as a software developer and since 2004 I've been working mostly with Microsoft technology.
I started out as a product developer, but after a few years I switched to a project company where my roles ranged from developer up to consultant and from team lead and coach to manager.
Eventually I switched jobs and focused on the consultant part but now I'm back where I started out and I'm building a product once again.
