What I'm Doing

I love what I do. I take great pride in what I do.

I have been working with web development in nearly 2 decades. I prefer to work with C# and MVC. The Content Management Systems I try to specialize in are EPiServer and Umbraco.

2. Tech Training

EPiServer is hiring me to educate their clients. I have trained both editors, administrators and developers in how to be better at using EPiServer as a cms.

My Resume

I have worked with around 100 websites. Only a few of them will be mentioned below.

Work Experience
1992 - Now

1992 - Now

CEO/Owner - The Cat Musketeer/Aimasan

I started my company Aimasan (and then later my new company The Cat Musketeer) 1992 (even though it took a couple of years until I began to focus on the web) and have since then helped a lot of companies/organisations with their websites. But I have also been employed in many companies/organisations (described below).

I have developed/worked with many websites through my company or through my employments (probably around 100 websites).

Right now I am helping a few clients with their websites (EPiServer & Umbraco) and developing some own websites (for example one on Microsoft Azure with ASP.NET 5.0, Entity Framework 7 and MVC 6).

I am also helping EPiServer when they hire me as a Tech Trainer for educating their clients (editors, administrators and developers).

In the end of 2015 I started an additional company called The Cat Musketeer.

2014 - 2015

Expert Services Consultant - EPiServer

Sometimes partners/customers had to customize their solutions a lot and needed more help than they could get from the support. Then they could hire us who worked in the Expert Services department. We helped them with for example code reviews, EPiServer Find, integrations with ADFS and performance optimizations. I worked with several international clients. Also worked as a trainer for partners and customers.
