Programming 6501 assembly and Basic on the Commodore 64

I have been programming since I was twelwe or thirteen. First Commodore 64 and ZX Spectrum BASIC, then moving to 6501 assembly. Later, various other BASIC dialects as well as Pascal and Perl, C/C++, Java, JavaScript, Ruby, Python and PHP.

After jazz- and pedagogic studies at the Royal College of Music in Stockholm, I worked as a musician and a teacher in (jazz/pop/rock) improvisation and ensemble playing. After a while, I joined Stockholm Tramways, where I drove trains and also worked as a traffic supervisor for the tramway system.

After that, I worked over 10 years at Ping Pong AB as a full stack web developer. Day to day work involved a lot of Java, jsp, PostgreSQL, CSS, JavaScript and more.

My current occupation is at Svenska Handelsbanken where I, among other things, do front end work for the Internet banking services and internal services.
“Front end” in this case means using a base system of Custom Elements together with things like React.js, TypeScript, CSS (and friends) to build working, useful and usable applications to be consumed by web clients.

In my “spare” time I have been focusing on JavaScript and node.js, but also done work in PHP and Ruby on Rails.

I keep myself updated about what is happening in the web development world by following and interacting with some interesting people via twitter, following mailing lists like ES-discuss (for future versions of JavaScript) as well as participating in the user group sthlmjs and going to conferences like and Jfokus now and then.
