My Professional History
During my university studies I created and published the Programmers Heaven CD-ROMs (2 of them) that I sold all over the world. Together they contain over 12000 source codes, tutorials, components and tools that I compiled and organized.
I Created my first website called Programmers Heaven, an online community for developers that ended up receiving over 750,000 visitors per month at its peak. The site became my full time job for many years. Running this website gave me a unique understanding in how to operate, administrate and promote web sites.
Created and operated a website called CodePedia, a Wiki for developers.
Co-authored a C# ebook called C# School that can still be downloaded online
After Programmers Heaven I worked for a few years as an Independent .NET consultant in Sweden implementing various systems for online marketing.
Co-founded Edument AB a consulting and training company with offices in Helsingborg, Göteborg, Malmö and Prague. Besides running the company with my cofounder Acke Salem, I worked as a consultant, architect and trainer. Co-created the cqrs.nu web site.
I was the main organizer for the Community Day conference. A popular one day conference that we arranged in Malmö, Göteborg and Stockholm with both local and international speakers. Visit communityday.se for more details.
I left Edument and resumed working as an independent consultant and trainer, focusing on .NET, Architecture and security.
That was my professional history, but we all have to start somewhere. Here are some of the highlights from my early years.
My journey began quite early on when I got my first computer, the Commodore VIC-20, in 1981. I ended up taking evening classes in Basic programming at the age of 11, and that’s when the foundation was set. I even ended up in a local newspaper in 1981.
A few years later, I got together with a few friends to create the Atari ST demo group Sync. Eventually, over the next few years, we released many demos and applications. I spent these early years experimenting and learning through DIY. In 1980, I co-authored Audio Sculpture, a sound-tracker music application for the Atari-ST written in 100% 68K assembly language that ended up getting sold all over Europe.
The DIY continued when I realized I wanted to develop games on the Sega Megadrive console unit, but there were no guides, documentation or hardware. So instead, I reverse-engineered the drive from scratch and created a development kit to connect to my Atari ST computer and wrote applications.
