About Me

Passionate Developer with a Security Mindset

I am a BCA Final Year student from Punjab, India, focused on building production-ready web applications while ensuring they remain impregnable to threats.

My dual passion for Full-Stack Development and Ethical Hacking (OWASP Top 10) allows me to architect robust systems. As an active NCC Cadet, I bring military discipline, leadership, and a structured approach to every codebase I touch.

Currently leveraging my GitHub Student Developer Pack to deploy and scale applications on modern cloud infrastructure.
