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.
