Have been working on a side project that focuses on sharing economy, allowing users to pickup and deliver groceries for others. Have already started working on the frontend for the web dashboard using React and plan to use React Native for the mobile app. But am in a dilemma, whether to build the backend myself for the MVP or use firebase for the backend. I need advise, has anyone use Firebase for such project and what are the pros and cons, what issues will i faced.

Note: My proposed stack for the backend is a Prisma database, GraphQL , Apollo and ExpressJS

Thanks in advance to everyone.
