01 — THE TRANSITION
From building enterprise systems
to strengthening trust.
At Walmart Global Tech, I built Java and Spring Boot services supporting enterprise inventory workflows while working directly with security, compliance, and operational controls.
That experience now informs how I approach ITGC and audit work: understanding the system, tracing evidence to control objectives, and translating technical findings into practical risk decisions.
Control evidence
Supported SOX documentation, test-cycle coordination, access reviews, and audit evidence preparation.
Risk reduction
Led security remediation, vulnerability-driven logging changes, incident RCA, and resource optimization.
02 — CORE CAPABILITIES
Engineering depth.
Controls experience.
Applied experience across access governance, change controls, security remediation, compliance requirements, and audit support.
Access Controls & SoD
Tested SAP roles, permissions, preventive controls, and segregation of duties during Finance 2.0 and Manufacturing S/4HANA implementations.
Change & Operational Controls
Maintained secure delivery through CI/CD, contract testing, scheduled reconciliation, observability, incident response, and root-cause analysis.
Security Remediation
Eliminated 1,500+ code smells and 100+ bugs with SonarQube and led a logging-stack migration to reduce vulnerability risk.
Audit & Compliance Support
Supported SOX 404 documentation reviews, test-cycle coordination, technical evidence, and control alignment across SOX, PCI DSS, and NIST 800-53.
