About this gig

I will design and implement a clean cloud backend for your app. It will be secure, scalable, and ready to connect to any frontend.


The default setup uses Firebase with Auth, Firestore, Storage, Hosting, and Functions. If you already use another stack, I can adapt to it.


You will receive clear documentation, maintainable code, and a working deployment that you can extend or scale later. This gig is ideal for startups or small teams who want a reliable base that just works.


What you will get

  • Authentication and database setup
  • Cloud storage and deployment
  • Secure rules and environment configuration
  • Optional frontend connection (Next, React, SwiftUI, etc.)
