I am in the process of building an MVP multi-tenant application (SaaS).
The MVP will be developed with Mean stack ( Node.JS /Angular 6) living on Amazon Web Services using ExpressJS for a REST API and mongoose to talk to Mongo DB for storage.
The web content is stored on S3 bucket with cors API call to the backend.
For authorization, we are planning to use Auth0 architecture.
We are planning our backlog with Trello and manage our code with github.
please send me a message if this project interests you.
