Custom ERP Quotation Module Development

I'm seeking a skilled full-stack developer to build the Quotation Module for a custom ERP system for an interior manufacturing company. This module will serve as the foundation for connecting with BOM, job cards, and production tracking in the future.

Key Requirements:

- Customizable templates
- Client management

Primary focus should be on quick generation of quotations, with a simple, form-based frontend interface for ease of use by non-technical users.

Tailwind CSS or Bootstrap (for styling and UI)

Node.js or Django (for backend logic and server-side)

Express.js (if using Node.js)

MongoDB or PostgreSQL/MySQL (for database)

PDF generation tools (like Puppeteer or jsPDF)

WhatsApp Business API (for approvals and client notifications)

Email automation (using SMTP, SendGrid, or Mailgun)

QR code generation and scanning (using libraries like qrcode, react-qr-reader)

AWS or Firebase (for deployment and hosting)

Admin panel creation and access control

Strong understanding of modular ERP/CRM structure

Scope of Work (Phase 1):
Build a quotation module with item-wise selection

Add production logic (auto BOM creation based on quote)

Develop a clean, minimal UI with dropdowns, minimal typing

Enable quote PDF generation and WhatsApp/email sharing

Add version control and approval workflow for confirmed quotes

Bonus (Not mandatory but good to have):
