Streamlined user access provisioning by automating group assignments based on role, reducing provisioning time by 40%, and increasing the accuracy of access control. Maintained 100% account compliance by implementing rigorous auditing practices and enforcing security policies for user access, reducing account lockouts, and unauthorized access incidents.

Managed privileged access for over 100 users across multiple secure environments, ensuring strict adherence to NSA compliance protocols.

Led the implementation of Role-Based Access Control (RBAC) standards across classified and unclassified systems, enhancing least-privilege enforcement, and reducing redundant access by 70%.

Collaborated with audit teams to ensure system access policies aligned with federal standards
