"His project was the best project I have seen in over 2 decades of teaching computer science. As I have also worked as an IT professional for many enterprise level worldwide corporations, I would rate Mr. Arji's skill as equal to a 5-10 experienced IT professional."
Project Overview
This Capstone Project represents a full-scale design and implementation of a secure, scalable, and highly available multi-site IT infrastructure for a simulated organization — NaviTransit. The project replicates the complexity of a real-world enterprise environment, built to support real-time transportation monitoring and intelligent route planning across three geographically distributed regions. It integrates advanced cybersecurity controls, layered network segmentation, and enterprise-grade service delivery.
Live Project: This project is fully deployed and operational. You can visit the company's website at navi.4rji.com
Implementation Note: All infrastructure, services, and security configurations were installed and operated from my personal home lab environment, demonstrating real-world applicability and performance.
