Full-Stack Dog-Walker Platform Build

Summary
Senior Backend Developer Needed — Dog Marketplace App (NestJS + Flutter Integration)

We are building Doggy, a dog walking/sitting marketplace app for Israel.

The Flutter app UI is already ~70% complete (~54 screens already built). We need an experienced backend developer/team to build the full production backend, integrate the Flutter app with live APIs, and build a small React admin panel.

Scope

Backend

• Reports/disputes
• Live tracking (MVP)
• Admin moderation tools

Flutter Integration

You are NOT building new Flutter UI screens.

A separate frontend developer handles UI.

You ARE responsible for:
• integrating all screens with APIs
• replacing mock/demo data
• loading/error states
• Socket.IO + FCM integration
• coordinating with frontend dev
