I am Ian Reppel (a.k.a. Hellström), PhD (theoretical physics). I have spent more than fifteen years building machine learning and data infrastructure at Spotify, Nubank, Bosch, Jua, and D2iQ. I work on ML infrastructure, quantum computing, and product strategy.

Write to me below if your problem requires rigour more than reassurance.

I do not respond to unsolicited sales or vendor pitches.
