Development of a Comprehensive Logistics Web Portal: Tms & Erp Integration with Ai Automation

We are seeking an experienced freelancer or team to develop a robust web portal for a logistics company. This system will integrate Transportation Management System (TMS) and Enterprise Resource Planning (erp) functionalities to streamline our entire operational workflow, from customer relationship management (crm) to final invoicing. The portal should be a comprehensive solution designed to enhance efficiency, reduce manual errors, and provide data-driven insights.

Key functionalities required include:
- Customer Relationship Management (CRM): Managing client interactions, leads, and sales processes.
- Order Management: Processing and tracking orders from initiation to delivery.
- Transportation Management: Planning, optimizing, and executing transportation activities.
- Warehouse Management: Inventory control, storage, and dispatch operations (service outsourced) same as other services involved that should be integrated manually.
- Invoicing and Financial Management: Automated invoicing, payment tracking, and basic financial reporting.

The system must feature several API integrations to connect with external services such as carrier systems, tracking platforms, payment gateways, and other relevant third-party tools. A crucial component of this project is the integration of an AI assistant to automate various tasks, which may include route optimization, predictive analytics for logistics, automated customer support responses, or intelligent data entry.

The ideal solution will be scalable, secure, and user-friendly, providing a seamless experience for both internal staff and external partners. We are looking for expertise in developing complex web applications with a strong focus on backend logic, database management, and modern frontend technologies, alongside proven experience in ai/ml integration and api development.
