I am Jermaine Ragsdale — a CISSP and AWS Solutions Architect who transforms complex compliance requirements into elegant, automated security solutions. My career spans Cisco, Truist, Fiserv, and Verizon, where I have led zero-trust implementations, cloud migrations, and regulatory compliance programs across Azure and AWS.

Beyond enterprise security, I am a passionate developer building algorithmic trading systems, Pine Script indicators rooted in ICT methodology, and full-stack cloud projects. I believe security should be invisible, automated, and uncompromising.
