Well, Lufthansa has an Analytics Center of Excellence. And that CoE does a very good job. One day, the CoE decided to promote their good work. So they asked me, a Data Scientist who built recommendation engines for them, to build an app.
So I built an iPad app. The goal: impress business partners at internal fairs. Users could swipe pictures, like the one with the turtle, to show if they like or dislike them. The app would then recommend the perfect flight destination. All based on the user's implicit preference expressed by swiping.
It was an exciting tech stack we built. It was my first project where I included UX Designers. It was the first Design Sprint I conducted. It was the time I fell in love with Product Management 💖.
