LogiFast - Personal Finance Tracking App

LogiFast is a backend application built using the NestJS framework, designed to function as an ERP system for logistics companies. The system aims to optimize business processes, reduce costs, and improve inventory management. It enables the automation of data entry, calculations, resource management, and delivery processes.

The primary goal of LogiFast is to provide an efficient mechanism for order processing, driver assignment, and vehicle management. It also aims to enhance logistics process analysis and control through business analytics and the Internet of Things (IoT). With integration to external services, the system facilitates automated route calculation and delivery cost estimation, minimizing human error.
