With over 15 years of experience, I specialize in leading engineering teams and delivering cutting-edge cloud-native platforms, identity systems, and distributed services. As Senior Engineering Manager at Capital One, I focus on platform engineering, enterprise IAM, and cloud architecture. My work includes spearheading the transition from RBAC to ABAC using OPA/Rego, implementing just-in-time authorization, and driving AI-assisted policy authoring for secure, scalable systems. My mission lies at the intersection of technical direction and execution, partnering with cross-functional teams to design and deliver robust solutions in regulated, high-scale environments. Passionate about enabling teams to succeed, I bring expertise in event-driven design, performance engineering, and reusable standards to create efficient, scalable systems.
