Ossian Hempel

Data engineer. Indie app developer.

I work with data engineering, have a background in data science, and build my own apps on the side. Most of them come from things I already spend time on: lifting, nutrition, and making daily systems less annoying.

A bit more about what I do.

I work as a data engineer now, after a few years closer to data science and analytics.
On the side I build apps around things I care about: lifting, nutrition, habits, and useful personal software.
This site is just a place to keep the projects and notes that are worth showing.
