πŸ‘‹, I'm Jan!

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

I'm currently building products at Personio πŸš€, driving employee productivity and happiness the workplace πŸ‘©β€πŸ’». Before that I co-built Back, and even earlier 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.

My Projects

GT81 is a personal, web-based version of the in-workout dashboard you can find in BEAT81 classes to help people measure their workouts during lockdown.

Built with Next.js.

After I got my Apple Watch a year ago I dug deep into my activity data to see what patterns I can discover and visualize with pretty charts.

Built with Next.js and Recharts. Data analysis in python.

The best places to eat, drink, and see in Berlin and Prague, as curated by my girlfriend and me.

Built with Nuxt and TypeScript, using Mapbox for maps and Airtable as DB.

An analysis of car2go vehicle availability data in Berlin based on time of the day and location.

Data crunching primarily done in python (using pandas and matplotlib) with Postgres as DB.
