Project description:
"Backend Architecture & Base System Setup
I need a backend developer to build Milestone 1 of a multi-client automation system for AC service companies.
This milestone focuses only on system foundation, not full automation logic.
Scope of Work (Milestone 1 Only)
1. Multi-Client Backend Foundation
Build the project structure to support multiple AC service companies.
Each client should have its own config:
Pricing
Services list
Reminder rules
Technician list
Branding name
2. Database Setup (MongoDB)
Create database connection
Create base schemas:
Clients
Customers
Technicians
Automations config
WhatsApp message logs (simple structure)

3. WhatsApp Cloud API Setup
Set up Cloud API webhook structure (I will connect my real Cloud API later).
Use your own test WhatsApp Cloud API during development.
Implement:
Webhook endpoint
Verification endpoint
Message receiving handler
Base reply handler
(No automation logic needed yet, only structure.)

4. API Structure
Create base API routes:
Add new client
Update client config
Test message endpoint
Create message router:
Identify client based on phone number or internal config
Pass incoming messages into the correct flow handler
5. Admin Panel (Basic Skeleton Only)
Simple placeholder admin interface (no UI design needed):
Login screen (fake static login ok)
Sidebar
Clients list page (static data acceptable)
Client detail page (empty placeholder)
UI is not important, just structure and routing.
6. Deployment & Environment Setup
Initialize project environment
Prepare .env structure
Host the backend on your preferred platform (Render/Vercel/Any Node server)
Ensure webhook URLs are live and working
What I Will Provide
Name: Test AC Service
Database choice: MongoDB
---
Important Notes
DO NOT use Twilio or WATI.
Must use WhatsApp Cloud API only.
Use your own Cloud API for development/testing.
My real Cloud API will be connected later during final testing.

Deliverables for Milestone 1
Multi-client backend
MongoDB database + schemas
WhatsApp Cloud API webhook working (test mode)
Base routing + message handler structure
Admin panel skeleton
Live deployed project
Postman collection for testing" (client-provided description)
