What the client needed
MyThings' four apps sent their notifications through an outside provider: a bill that grew with every device, the customer list sitting with a third party, and when an order notification didn't arrive nobody could say why.

Pushbib
A self-hosted push notification platform
Our roleArchitecture & full build — backend, dashboard and mobile SDK
01 — Overview
About the project
A push platform the company runs on its own server: it reaches millions of phones through Firebase and Apple directly, with no third-party subscription and no customer data handed to anyone — with a full dashboard and a React Native SDK.
How we built it
We built Pushbib from scratch: a Node.js server with MongoDB and RabbitMQ that sends through FCM and APNs directly, with one lane for order notifications and another for campaigns so a big broadcast never delays an order. A React dashboard to write a message, preview it on Android and iPhone, test it on the team's phones, then send or schedule it — with approvals and per-app permissions, targeting by segments, tags and location, per-device delivery tracking, and a health monitor for every part of the system. And a React Native SDK that installs in three lines, with no Firebase setup inside the app.
