Hi all!

I'm Erik Bjäreholt, a Swedish software engineer and independent researcher. I'm the founder & lead developer of ActivityWatch, and I've been doing Quantified Self stuff for over a decade (since I was in high school 2010-2013).

I wrote my master's thesis on classifying the brain activity of software developers with EEG.

I've been watching all the "official" Quantified Self stuff from afar for a while now (since Gary Wolf had his TED talk in 2014) and on this day of writing (2022-11-3) I finally discovered the weekly calls, so going to try and chime in every now and then.

You can learn a lot about me from my other profiles across the internet:
