Message

At Medtronic, I lead cloud security strategies across AWS and Azure and serve as an AI Security Liaison. I’ve designed guardrails and risk assessments to protect cloud services, enterprise applications, and sensitive model-training data.

I’ve also designed security measures for AI models including DeepSeek, Claude, and OpenAI, and trained incident response teams on cloud and AI-driven systems. My work includes security baselines, governance processes, and safeguards against adversarial attacks and unauthorized access.

Before Medtronic, I worked in cloud and application security at Lincoln Financial Group, Roostify, nVisium, and Fishnet Security Consulting. Earlier, I developed applications at JCPenney and Corporate Business Solutions, Inc.; I hold CISSP, CCSP, and AWS certifications, along with a post-graduate program credential in AI and Machine Learning from Purdue University.
