Cross-Platform Solution: Apps & Backend Development

Project Title: Mobile App + Web App + Admin Panel + Backend Development (Flutter, React, Node.js, PostgreSQL/MongoDB)

Description:
I am looking for an experienced team (or individual full-stack developer with support) to build a cross-platform solution that includes:
• Mobile App (Flutter) – for iOS and Android
• Web App (React) – for end users (same features as mobile, browser-accessible)
• Admin Panel (React) – for content & user management
• Backend (Node.js + PostgreSQL/MongoDB) – APIs, authentication, and integrations

The project will follow a 3-month roadmap with milestone-based payments.

Core Requirements (MVP Scope):
• Mobile App & Web App (Flutter + React):
• User authentication (email/OTP)
• Profile management
• Content feed / listings
• Push/web notifications
• One AI feature integration (e.g., ChatGPT API)
• Admin Panel (React):
• Role-based login (Admin/Editor)
• CRUD for content and user management
• Basic analytics dashboard (users, sessions, activity trends)
• Backend (Node.js + PostgreSQL/MongoDB):
• Secure APIs for mobile, web, and admin
• User roles & permissions
• Audit logs & basic rate-limiting
• Integration with OTP provider & push notification service
• Hosting & Infrastructure:
• Deployment on AWS/DigitalOcean/GCP
• SSL, backups, monitoring, staging & production environments

Deliverables:
• Complete source code in my GitHub repo
• API documentation + Postman collection
• CI/CD setup for mobile, web, and backend
• Deployment guide & admin manual
• Handover and training after UAT

Budget & Timeline:
• Timeline: ~as soon as possible
• Budget: ₹X–Y (please quote your best price)
• Payment: Milestone-based (Design → Development → UAT → Live Deployment)

Other Notes:
• Must follow security best practices (JWT, HTTPS, encrypted DB, backups)
• Preference for prior projects in Flutter + React + Node stack
• Future support/AMC can be discussed separately
