I am a cybersecurity enthusiast with a strong focus on web and API security, vulnerability research, and ethical hacking. My passion lies in discovering security flaws, automating reconnaissance, and developing offensive security solutions to strengthen digital defenses. I have developed custom automation tools like Subdominator and Dnsprober, which showcase my ability to create effective security solutions.

In my role as a Digital Forensic Analyst with the Tamil Nadu Police, I developed detailed reports from forensic examinations and streamlined evidence collection processes, significantly reducing case backlogs. As an Automation Tool Developer at Apseris Security, I created an advanced reconnaissance tool that automates asset discovery, integrating various security checks to enhance organizational security. My freelance work as a Penetration Tester has allowed me to identify critical vulnerabilities in major platforms, contributing to improved security postures for numerous organizations.
