About Me

Hello there! I'm a full-stack developer with roots deeply planted in the picturesque landscapes of Northern Jutland, Denmark. My coding journey began rather innocently in the early 2000s, when I discovered Microsoft FrontPage on our family's first proper computer—a towering beige box that hummed with possibility. What started as curious clicking evolved into a genuine passion that has now shaped over a decade of my professional life. Those early days of trial and error taught me that persistence often matters more than perfection, a philosophy I still carry with me today.

Penguins are elegant, resilient, and thrive in tough conditions—kind of like developers at 2 a.m., wrestling with that one bug that just won't quit. Plus, Tux the Penguin, Linux's suave and slightly cheeky mascot, perfectly matches my Linux-based workflow. Stylish, symbolic, and just quirky enough to keep things interesting, the penguin felt like my spirit animal in tech.

And let's be real—penguins are hilarious. They waddle like they own the place, slide on their bellies for fun, and somehow still look like they're ready for a red-carpet event. Add their teamwork and ability to handle life in the toughest climates, and they're basically the developers of the animal kingdom. How could I not choose the penguin?
