paul lodder


I'm a (freelance) data engineer/scientist with a MSc in Artificial Intelligence (University of Amsterdam), and passionate about research into the therapeutic potential of psychedelics.

I obtained my BSc at Amsterdam University College, where I focused my studies on biomedical sciences and computer science. Since graduating in 2018 I have been working as a data scientist and data engineer alongside my MSc studies.

I'm also an emacs and org-mode evangelist.


Some recent (on-going) projects in no particular order.

zon op je bakkes
I combined some open datasets to compute how much sun the outside seating areas of different bars and restaurants in the Netherlands receive. Although we started zonopjebakkes in Amsterdam, the site gained national traffic and over 3500 terraces have been added by users since.
Developing scalable software to have creators gain insight and control of their royalty income.
