Assistant City Auditor at City of Houston, automating ITGC monitoring to increase audit coverage by 25%.

United States

Message

At the City of Houston, I identified critical vulnerabilities across SAP and cloud infrastructure and made risk-based audit recommendations. I also automated ITGC monitoring using AuditBoard, increasing coverage by 25% and reducing manual testing by 40%.

At Deloitte, I managed IT SOX programs for enterprise clients, reducing overdue audit issues by 65% and repeat findings by 70%. I evaluated controls across SAP, cloud, and cybersecurity domains and applied NIST AI RMF principles to AI system audits.

Earlier, I tested ITGCs and application controls at PTP/Deliver-Health Solutions and Nuance Communications, including SOX controls, access management, and change management. I’m CISA-certified and work with frameworks including NIST, COBIT, and ISO 27001.
