Full-Stack Developer for Doggy Marketplace App

# Doggy Dog Marketplace App
## Backend Developer Needed — NestJS + Flutter Integration

## Project Overview

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

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.
