About Me

I don't just find vulnerabilities —
I think like the adversary.

An aspiring cybersecurity professional pursuing BTech in Computer Science & Engineering (Cybersecurity) at VIT Chennai. Experienced in penetration testing, web application security, and vulnerability assessment.

I interned at Cyber Dome, Kerala Police — analyzing phishing campaigns, configuring OPNsense firewalls, exploring firewall bypass techniques, and setting up site-to-site VPNs. These hands-on battles laid my foundation for offensive security and red teaming.

As Membership Chair & Web Lead at ACM VIT Chennai, I manage and secure the chapter's website while overseeing technical operations for community events. Skilled at developing innovative solutions and leading projects in fast-moving tech communities.
