Hello, I'm
Jannik
A Curious Product Manager with a maker’s mindset and a soft spot for great UX.
About Me
I'm a Product Manager with a passion for creating digital products that make a difference. With experience in both B2B and B2C environments, I specialize in turning complex problems into simple, elegant solutions.
When I'm not building products, you can find me exploring new technologies, reading about design, or enjoying the outdoors.

Projects & Products
In 2025, I quit my job at CHECK24 and took six months off to learn programming. Why? Because I genuinely love building products. I realized that with a bit of coding knowledge, I can leverage AI to create things entirely on my own—and I think that's pretty exciting - so I went all in.
