Moin.
This is Florian from Hamburg.
Welcome to my blog. I write about coding, data projects, and sometimes about my personal life.
My professional story
I am interested in building exciting technology with great teams.
I have spent some years building products that use deep learning to understand human motion in video: Anything from video-powered workout apps to gesture recognition for the automotive industry.
People often forget that building these AI products requires a ton of “boring old software” on the side: Web apps for data management, build pipelines for deliverables, deployment of web services. This has now led me back to a broader space of simply building good software – with or without AI inside.
Working in both product and service companies over the years has taught me to put the user at the center of every product decision – a good reminder when working with technology.

Selected Projects

Side project, web development
A self-hosted sports guessing game that 16 friends of mine and I used during the Eufa Eurocup 2024. Backend is Go, frontend is plain vanilla JS and hand-crafted CSS.
I wrote an article about the project.

Hackathon, Data Science
In April 2020, I participated in the AI for Good Hackathon, taking place remotely. Our team of four analyzed satellite and location data, practiced our Data Science skills, and created visualizations.
Side project, web development
3 friends and I co-founded Album Up, a premium service for photographers to deliver photos to their clients. The service was online from 2016 to 2021.
