πŸ‘‹, I'm Jan!

I'm a product manager living in Berlin, who enjoys building new products and drinking old scotch.

I currently lead product in Back πŸš€, building products for the workplace πŸ‘©β€πŸ’». Before that I was leading the product teams in Marley Spoon 🍱 and Fyber πŸ“±.

In my free time I'm on a quest to make the best gin basil smash 🍸. I also ride my bike 🚴 around Berlin and obsess about coffee β˜•οΈ.
