Passionate About Backend Development
I've been coding since I was 14 years old, turning my early passion into a professional career spanning over a decade. Based in Stockholm, Sweden, I currently work as a Backend Developer at OutdoorMap, where I build scalable systems using Ruby and Elixir.
My entrepreneurial journey includes running Honeybee.it and XMLTV.se — a 15-year venture where I collected, produced, and sold EPG data (TV Guides) to major Swedish newspaper organizations and cable operators.
I'm deeply committed to the open-source community, building libraries and tools that solve real problems for developers worldwide.
