Human Resource Management System (HRMS) A

Human Resource Management System (HRMS)

A full-stack Human Resource Management System designed to streamline employee operations, attendance, leave management, payroll, and organizational administration through a secure and scalable web application.

What I Built

I developed the HRMS backend using ASP.NET Core Web API with a structured architecture focused on maintainability, security, and scalability.

The system includes:

👥 Employee Management — Create, update, manage, and view employee information.

🏢 Department Management — Manage departments and organizational structure.

🕐 Attendance Management — Track employee attendance and working records.

🌴 Leave Management — Submit, manage, and approve employee leave requests.

💰 Payroll Management — Handle employee salary and payroll-related information.

🔐 Authentication & Authorization — Implemented JWT authentication with refresh tokens.

👤 Role-Based Access Control — Different permissions for Admin, HR Manager, Manager, and Employee roles.

📊 Reports — Provide HR-related data and operational insights.

🔔 Notifications — Support notification workflows for important HR activities.

Backend Architecture

The backend was built with ASP.NET Core Web API following Clean Architecture principles.

Architecture: Domain → Application → Infrastructure → API

I implemented:

Repository Pattern

Unit of Work

Dependency Injection

Entity Framework Core

RESTful API design

JWT + Refresh Token authentication

Role-Based Authorization

SQL Server database

DTO-based API communication

Structured exception handling and validation

Frontend

The frontend was developed using React.js, providing an interactive dashboard and user interface for different HR roles.

The application communicates with the ASP.NET Core API through secure authenticated API requests.
