Workforce Management ERP System This project is a comprehensive ERP solution for workforce management, designed to streamline operations for companies that employ laborers for construction or home service tasks. The system automates task assignments, tracking, and reporting, providing companies with a seamless way to manage their workforce efficiently. Key features include: Task & Labor Management: Assign laborers to specific jobs at construction sites or homes with real-time tracking. Custom Calendar: Schedule tasks using a fully integrated calendar, with the ability to export schedules in PDF format. Notifications: Firebase push notifications to keep laborers and managers updated about assignments, changes, or urgent tasks. AWS Integration: Uses AWS services, including S3 buckets for secure storage of documents, images, and reports. Optimization Techniques: Implements virtualization and memoization to ensure smooth performance even with large datasets. Reporting & Analytics: Generate reports and summaries of labor performance, task completion, and project progress.
