Hi, I'm Asbjørn Ulsberg and I've been programming professionally for more than 20 years and as a hobby for more than 30. I have a passion for software architecture and spend a lot of time thinking about modeling and naming things. The web has always been close to my heart, so I spend time in IETF and W3C working groups to make it better.

When I'm not working, I enjoy spending time with my wife and daughter as well as participating in the demoscene and making music with my alter ego Bitbear. I love creativity and continuous improvement, which are two of the driving forces that get me out of the bed every morning.

I've been working as a backend developer, frontend developer, CTO and architect, in all sorts of programming languages, ranging from Visual Basic to C, Perl, Ruby, Python, PHP, C#, JavaScript, Bash, etc. I therefore consider myself polyglot and "full-stack", whatever that means. I enjoy all parts of development, appreciate most programming languages and find the freedom to use the right tool for the job a liberating, creative and rewarding experience.
