Mobile ERP - Workforce Management
A mobile ERP solution for employee attendance, shift management, and payroll access with geofencing-based check-ins.
Timeline
Q3 2024 - Q4 2024
Tech Stack
Flutter (Dart), GetX (State Management), OpenStreetMap + Leaflet, Geolocator & Geofence Service, Device Info Plus (Mock Location Detection), Dio (API Requests), Shared Preferences & Get Storage, File Picker & Open File (For document uploads)
Overview
This project was developed for a Japanese company while working under Nodewave. Managing employee attendance accurately is a challenge for many companies, especially with remote or multiple-location teams. Mobile ERP is a workforce management solution that enables employees to check in securely using geofencing, track shifts, request leave, and access payroll data seamlessly. The app ensures security, preventing location spoofing and unauthorized check-ins.
Features
Geofencing Attendance
Ensures employees check in within a 100-meter radius of the workplace.
Selfie Verification
Requires employees to take a real-time photo as proof of attendance.
Mock Location Prevention
Uses Device Info Plus and backend validation to detect location spoofing.
Secure Authentication
Implements access & refresh tokens stored with Flutter Secure Storage.
Shift Management
Employees can view and request shift changes based on company policies.
Leave Request System
Submit leave applications digitally, with document uploads for approval.
Payslip Access
Employees can view and download their monthly salary breakdown in PDF format.
Objectives
- •Implement secure geofencing-based attendance tracking with OpenStreetMap.
- •Develop a robust authentication system with session management.
- •Enable real-time shift management to assign or swap shifts dynamically.
- •Ensure data integrity and security against GPS spoofing and mock locations.
