About Boštjan
I'm a digital nomad originally from Slovenia and now based in the amazing Canary Islands, Spain, where I am connected with the international community.
Career-wise I became an experienced full-stack programmer specialising in server-side software. I have a number of years of experience developing and programming software for various companies. I have been passionate about programming since my early days and my current role as a back-end developer is the perfect combination of everything that I enjoy about the industry.
As an Electrical Engineer, I also have some experience with firmware development and basic electrical engineering (prototyping).
