🚀 VProfile DevOps Mega Project

End-to-end DevSecOps showcase — from local Vagrant environments to full AWS cloud migration, demonstrating real-world production-ready workflows.

A three-tier Java web application meticulously designed and built to demonstrate the complete DevOps journey:

• Traditional manual provisioning → setting the baseline
• Infrastructure-as-Code automation → enabling repeatable, scalable setups
• Cloud migration to AWS → leveraging auto-scaling, load balancing, and private networking
• Future vision → complete cloud-native DevSecOps with CI/CD, container orchestration, and security integration

This project isn’t just a demo — it’s a living portfolio piece crafted to showcase real-world problem-solving skills, enterprise-grade architecture, and modern DevOps best practices.
