Wout Swinkels

My interests have varied over the years, but tech has always been a constant. During my electrical engineering studies, I initially gravitated toward electronics. However, along the way, I discovered the joy of programming and have been immersed in it ever since.

Currently, I am interested in Nix, virtual reality, and open-source software and hardware. I’m always eager to learn new and interesting programming languages, tools, frameworks, and architectures, such as RISC-V. The only thing that limits me in this pursuit is time.
