Volunteer for DataKind (http://www.datakind.org/), a charity that connects "data professionals" (in the broad sense of the term) to charities who have problems to solve and the data to solve them, but not the resources to do it!
They organise different types of projects: DataDives, which are hackathon-type events and focus on data exploration and analysis; and DataCorps, longer term projects (a few months), where a team of volunteers will team up on a more project for the client charity.
They are looking for volunteers for a wide range of roles, including data scientists, programmers with experience with ML, dataviz experts, project managers, etc.
