For My Verve And Passion

Outside the professional sphere, I love spending time with my family. I’m into sports and if there is time left I like tinkering with microcontrollers and 3D printing and enjoy working with different materials. Often this is accompanied by an eclectic mix of music and indulging in scientific topics, coffee and healthy food.
