About Me

Hey! I’m Dennis, also known as DDob. Music has always been my biggest passion, and it’s what led me deep into the world of technology. I love digging into complex systems, peeling back the layers, and turning challenges into elegant solutions. When I’m not coding or experimenting with new technologies, you’ll probably find me producing music or exploring ideas at the intersection of both worlds.

I occasionally teach as well — sharing knowledge and helping others level up is something I truly enjoy.

Below is a look at the path I’ve taken so far:

Software Engineer
