Firebase backend for web and mobile apps

I build production-ready backends on Firebase and wire them straight into your web and mobile front-ends. If you need to launch fast without hiring a DevOps team or renting servers, this is exactly what I do every week. I set up Authentication with email, phone and social sign-in, model your data in Firestore or the Realtime Database, and write Cloud Functions that carry your business logic close to the data. The result is a backend that scales on its own, updates clients in real time, and costs you only for what you actually use.

My work covers the whole path from an empty project to a live product. I design the data structure so reads stay cheap and queries stay fast, lock everything down with security rules that I test rather than guess at, and connect push notifications and analytics so you can see how people use the app from day one. For web I hook the SDK into React, Vue or plain JavaScript; for mobile I integrate with native iOS, Android and cross-platform Flutter builds. Hosting, custom domains, storage for user files and scheduled background jobs are all part of the package when you need them.

You get clean, commented code, a short written guide to your project, and a backend you can keep growing without rewrites. I explain every decision in plain language, stay available after launch for questions and fixes, and hand over full ownership of the Firebase project so nothing is locked to me. Tell me what your app should do and I will map it to the right Firebase services and a realistic timeline.

— Auth: email, phone, Google, Apple and anonymous sign-in
— Firestore or Realtime Database with tested security rules
— Cloud Functions, push notifications and analytics
— Web, iOS, Android and Flutter integration
