About

I live in NYC and since Feb 2015 I’m the Head of Engineering and Product of Better – a company rethinking how mortgages are done. At Better, I manage a team of about 40 engineers and 10 product managers.

Before Better, I was at Spotify for nearly 6 years. I spent 2.5 years in Stockholm managing the “Analytics” team and then 3.5 years in NYC building up and managing the machine learning team. I built the first version of (and most of the sauce still powering) Spotify’s music recommendations, such as “Related Artists”, Radio, Discover Weekly, etc. At Spotify I also open sourced a couple of tools, including Luigi – a workflow engine with 10,000+ stars and 200+ contributors on Github, and Annoy – a library to do find approximate nearest neighbors in high dimensional spaces.

I joined Spotify after graduating with a M. Sc. in Physics from KTH in Stockholm, where I’m originally from. During my university years, I did a few internships, including a six month stint at Google in Zürich. I also worked briefly with high frequency trading and a couple of other things. During university and high school I got involved with programming competitions. I have a gold medal from IOI and I participated in the ACM-ICPC world finals twice. In high school I won the Swedish physics competition as well as the Swedish programming competition.

Besides blogging, I also tweet random things every once in a while. I also occasionally write code for fun in my spare time, and a few silly things can be found on my personal Github.

I enjoy giving talks if there’s something I know a lot about. Previously I’ve talked about approximate nearest neighbors, Luigi, and machine learning for music recommendations. I am the co-organizer of the NYC Machine Learning meetup which has talks once a month.

When I write code I usually do it in Python, but I’ve been using a dozen different languages since I started writing code 25 years ago. Most of what I’ve been doing last few years has been machine learning, data engineering, and backend development. I still write code some fraction of my time, but focus a lot more on management now, in particular recruiting and how to build a performance culture.

What about stuff outside of technology? Some misc facts about me:

  • I live in the West Village, NYC
  • I’m married, and with my wife Bridget I have two daughters: Astrid and Ann
  • On top of that, I also have two cats
  • I stopped eating meat in 2011
  • I never owned a TV or a car (in fact never had a driver’s license)
  • I’ve been to 45 countries, and I once hitchhiked from Berlin to Barcelona
  • When I listen to music it’s usually electronic (and I actually played the piano actively for 10+ years)
  • I speak Swedish, English, and German
