Key code examples from this financial software project, showcasing authentication, calculations, visualizations, and data management implementations.
A comprehensive platform for managing personal loans online with separate interfaces for administrators and customers.
This full-stack web application enables secure loan management for both administrators and customers. Administrators can manage users, loans, and payments, while customers can track their loan statuses and payment history. The application streamlines the entire lending process with features like authentication, payment tracking, email notifications, and detailed analytics. The system is designed with role-based access to provide different views and capabilities depending on user permissions.

The Personal Loan Management System is a full-stack web application designed to streamline loan management processes for both administrators and customers. It features distinct interfaces, robust authentication, detailed analytics, and automated notifications.
User interfaces for both admin and customer portals, designed for responsiveness and intuitive interaction.
Handles business logic, API endpoints, authentication, and data interactions.
Relational database for structured storage of all application data.
Tools and practices for development, testing, and deployment.
Users authenticate through the frontend using JWT tokens, with role-based access controls distinguishing between admin and customer capabilities.
Admins can create, edit, and manage loans, while customers can view their loan details. Email notifications inform customers of any changes.
The system tracks payments against loans, with recent payments being editable. Each payment updates the loan status and triggers notifications.
All transactions are stored in the MySQL database, ensuring data integrity and allowing for comprehensive reporting and analytics.
Ensures secure and appropriate access levels for administrators and customers.
Interactive dashboards provide insights into loan performance and customer payment trends.
Email alerts for loan updates, payment reminders, and other critical events.
Full CRUD operations for managing users, loan applications, and payment records.
The system is divided into client (frontend) and server (backend) components, each with its own installation process:
git clone https://github.com/Nardos-Tilahun/Personal_Loan_Management.git
cd Personal_Loan_Management
# For frontend
cd Client && npm install
# For backend
cd ../Server && npm install
Running the application requires starting the necessary services:
# Start backend
cd Server && nodemon app.js
# Start frontend
cd Client && npm run dev
The application will be available at http://localhost:3000
Building this full-stack system involved several complex challenges that required innovative solutions and professional growth.
I faced difficulties designing an intuitive and engaging main page that would represent the platform effectively. The UI needed to be professional while remaining user-friendly for various stakeholders.
Since this was a cash-based system, payments needed to end in round figures (e.g., $10,000 instead of $10,541.50). I needed to create a system that would divide payments appropriately across terms while ensuring the total amount was covered without overloading customers.
As my first full-scale real-world project, I faced significant time pressure to deliver a functioning product while learning new concepts and technologies simultaneously.
Throughout the development process, customer requirements frequently changed, requiring flexibility and adaptability in the system architecture.
Despite these challenges, I successfully delivered a full-stack application that provides a comprehensive platform. The system now efficiently handles all core requirements while maintaining high standards of security and user experience.
