About me

Hi, my name is Christian, but my friends call me "Joker". Feel free to do the same. But I need to tell you that I'm bad at telling jokes.

I discovered my passion for programming when I was 9 after my father gave away my beloved dog. To honor his memory, I built a website filled with pictures of him. That's where my love affair with coding began. During high school, I took several graphic design courses and developed a strong interest also in UI design.

In my previous role as a consultant, I specialized in developing custom web applications. There, I had the opportunity to work for big companies across various industries like automotive, tourism, airlines, robotics, and medicine. Unfortunately, my previous projects were confidential. That's why I don't have a portfolio here yet. After years of experience in large corporations, I've ventured into freelance work.

I would love to hear from you and discuss our next project!
