Security Engineer  ·  AppSec  ·  Offensive Security  ·  AI Security

Breaking systems to build better ones. 4+ years securing 2M+ users at Zoho. MS in Cybersecurity from UCF. Now engineering security tooling at the intersection of AI and Cybersecurity.


// what i do

Offensive Security

Breaking things to build them stronger. I hunt for hidden flaws through penetration testing, exploit research, and competitive CTFs.

🤖

Agentic AI

Building autonomous systems that think and act. I design multi-agent frameworks and LLM tools to automate complex workflows and boost security.

🛡

Application Security

Securing code from the inside out. I focus on threat modeling, fixing vulnerabilities, and baking automated security directly into the pipeline.
