Prodex Enterprise Management System 🏢

Official Internship Project | Java Full-Stack Development

📌 Project Overview

Prodex is a comprehensive Enterprise Resource Planning (ERP) and Procurement portal developed during my internship at Xworkz. The system is designed to streamline organizational workflows, manage member lifecycles, and automate product procurement processes with high security and performance.

🛠 Key Features & Logic

🔐 Advanced Security Suite

• Credential Protection: Implemented BCrypt hashing for sensitive data storage.
• Brute-Force Prevention: Engineered a state-driven account-locking protocol that triggers after 3 failed login attempts.
• Secure Recovery: OTP-based password resets with automated background tasks to clean up expired tokens every 2 minutes.

📦 Procurement & Workflow Automation

• Lifecycle Management: Members can initiate purchase requests; Administrators can approve, reject, or comment via a centralized dashboard.
• Smart Reminders: Integrated ThreadPoolTaskScheduler to send asynchronous email notifications to admins for pending requests (24h/48h intervals).

📊 Performance Optimization

• Geo-Data Service: High-performance AJAX mapping using a 47MB JSON master file, loaded into memory at startup via @PostConstruct for zero-latency lookups.
• Scalable UI: Implemented server-side Pagination and Named Queries to ensure the system remains responsive even with thousands of records.

💻 Technical Stack

• Backend: Java 8, Spring MVC (5.x), Hibernate (JPA 2.1)
• Database: MySQL 8.0
• Frontend: JSP, JSTL, JavaScript (AJAX), Bootstrap 5
• Automation: Spring Task Scheduling & JavaMail Sender
• Build Tool: Maven
