AutoEngage - WhatsApp Follow-up Engine

Overview

AutoEngage is a system for businesses to automatically send and manage follow-up messages when customers don't respond to initial communications. It demonstrates full-stack development skills using React, Node.js, Flutter and automation tools.

Target Audience

• Small businesses (salons, gyms, tutors)
• E-commerce stores
• Service providers

Problem Statement

Businesses lose potential customers when they fail to follow up after initial contact. Manual follow-up is time-consuming and inconsistent.

Solution

A system that automatically:

1. Sends initial messages to customers
2. Tracks if customers have replied
3. Sends follow-up messages after a set time if no reply
4. Provides analytics on response rates

• Backend: Node.js with Express
• Mobile: Flutter app with WhatsApp-style UI
• Automation: n8n (open source alternative to Zapier)
• Database: Firebase/MongoDB (free tier)
• Messaging Simulation: UI in Flutter + backend logging

Core Features

1. Admin Dashboard

MVP Scope

• Basic admin panel with message sending
• Simple Flutter app with inbox
