I'm working with, and I'm one of the founders of, the company Qrendo AB, which is based in Stockholm, Sweden. We're specialists in IT architecture and IT security, and our passion is helping you, the customer, to get requirements with quality, using IT architecture and IT security as our main tools.

I've got a technical blog, where I discuss various things around software and related things such as productivity, and a personal development blog (in Swedish), where I look deeper into everyday psychological phenomena, with the purpose of escaping from The Matrix. Just kidding, but there's definitely something to gain from seeing through some of the most common misconceptions about what's going on in interactions with other people (and yourself)!

If you're interested in software or systems architecture (and not only the web application or enterprise subtypes of architecture), then you should read my series on evaluating software architectures, where I explain the ideas behind the Software Architecture Analysis Method (SAAM), and the Architecture Tradeoff Analysis Method (ATAM). These methods might seem abstract, but there's some reasonably deep wisdom and simplicity buried in the details.

Although I don't work in science any more, If you're interested in a summary of what I've done, please have a look at my most recent scientific publication (2005): a chapter in Handbook of Temporal Reasoning in Artificial Intelligence (or pick the Amazon page), together with Peter Jonsson. Quite fun to read if you're the kind of person that likes those kinds of things.

I've got quite a lot of publications from my previous life in science; please check them out if you're interested!

For those who like mathematics, I'm still keeping the old compendium on Abstract Algebra (in Swedish) online, that I wrote together with a friend, Pontus Gagge, long ago (which is 1993). Mathematics is timeless! It's actually quite good for learning the topic.

For my daily planning and acting, I've using David Allen's Getting Things Done (GTD) system since 2005. At times, I coach people in using that methodology for "stress free productivity", if you believe that this is possible. :-)
