Ten years in the software development industry have taken me from a developer, to a tester, to a writer to an owner.

Personally I am interested in design, photography, keeping fit and working the stock market.

You can follow me on Twitter ( or using any of my blogs:

  • (EN) - software development and productivity
  • Digital photo guide (EN) - photography and photo editing
  • PM Karlsson (SE) - stock market and finance
  • Hej, Martin här. (SE) - personal just about anything

Strange fact; I have designed a coffee mug a few years ago which is currently being sold in the US.
