Hello! I'm Jesús, a computer engineer from Cantabria, Spain, with a passion for all things tech. When I'm not tinkering with gadgets or building little tech projects, you'll often find me hiking wooded trails or exploring mountain peaks. I'm always eager to learn and experiment with new tech, and I'm a big fan of open source software - so much so that I contribute to various projects in my free time!
One of my coolest creations is rjLab - a project I started back in 2017. At first, it was just a test server for tinkering with all sorts of computing fun, from linux or web dev to networking. But over time, it's grown into a full-blown platform for my own projects, as well as a hub for services I offer to family, friends, and the community. Basically, it's a sweet tech playground where anything goes!
