Ghost and Storing Member Information


I’ve been experimenting with Ghost for the last couple months and i was wondering if other developers could share their path to storing specific user generated content Lets say a member signs up and generates a json object with some data and images. What have so far been succesfull or easy to store this information i’m thinking of integrating (Firebase, Directus, Gcloud or amazon) or can you use Ghost and Rely on Ghost itself to store this information?
