We're a group of about 20 active CorrelAid network members. We meet regularly to code and learn R and Python and brainstorm ideas for projects with local NGOs. We also organize MeetUps like the Data Dialogue.
If you want to participate or get in contact with us, just write us an e-mail to email@example.com!
DSSG Berlin is another wonderful organization for Data Science For Social Good in Berlin with whom we work closely.
