About Me

Hello! I'm Dhruv, a 2nd year Computer Science student at VIT Chennai with a passion for cybersecurity, full-stack development, and mobile app development using Flutter.

I specialize in building secure applications and cybersecurity tools. My recent projects include a full-stack event management app with Flutter and Node.js, and various Python-based security tools for PDF password cracking and subdomain enumeration.

When I'm not coding, you can find me exploring new security techniques, contributing to open-source projects, or participating in hackathons to solve real-world problems.
