Impact

Results

Attendance

Managers can reliably track employee attendance based on assigned shifts, even while off-site

Payroll

Payroll is automatically calculated using base salary, attendance, overtime, and leave records, reliable calculations

Shift

Shift schedules can be configured weekly and adjusted dynamically based on operational needs

Employees

Managers can easily add or remove employees, with generated accounts granting direct access to the employee portal

The Problem

Niaga Jaya’s management faced difficulties tracking employees because the manager was frequently off-site. Manual coordination made it hard to monitor attendance, shifts, and payroll accurately, creating a need for a centralized system to manage employees remotely and reliably.

The Solution

Employee management with centralized profiles and role separation
Attendance tracking using geofencing with precautions to prevent abuse
Automated payroll calculated from attendance and leave records
Leave management with email-based approval workflow
Multi-level approval workflow (OR/AND)
Shift management with configurable automatic weekly scheduling
Employee-facing portal for check-in and leave applications
Multi-entity support to manage multiple stores under one company
Clear separation between Admin and Employee interfaces

System Design

The system uses React.js for the frontend and Go for backend services, with shadcn/ui to standardize and accelerate UI development.

Challenges

Preventing attendance misuse such as fake GPS or remote check-ins by implementing device checks, geofence validation, and warning triggers for suspicious activity
Handling GPS location inaccuracies, a known browser limitation, while continuously improving validation logic
Designing a user-friendly and consistent interface using shadcn/ui for both admin and employee workflows
