What I'm looking for

I’m looking for an AP and compliance-focused role where I can ensure SOX accuracy, streamline invoice and supplier workflows, and support a high-performing team. I want clear metrics, continuous improvement, and strong ethical standards.

I’m an AP Principal Accounting Specialist with experience auditing employee expense reports, verifying invoice entry into financial systems, and driving 99%+ accuracy through disciplined SOX controls. At National Instruments – Emerson Electric, I maintained 100% SOX compliance during audit periods while managing vendor relationships, corporate account workflows, and supplier onboarding.

I also bring strong leadership and process-improvement experience from supervising teams, balancing daily workloads, and reducing processing backlogs through workflow analysis and training programs. With a background that includes customer service and financial operations, I’m known for high ethical standards, attention to detail, and efficient ticket management using tools like ServiceNow and JIRA.
