Internal audit tools and analytics built for practical audit execution.

I build audit-focused Excel tools, Power BI dashboards, workpaper templates, analytics apps, and governance workflows that help improve coverage, reduce manual effort, and make audit work more review-ready.

Prompt engineering + AI governance

AI-supported audit documentation needs controls, not just better writing.

My prompt engineering framework demonstrates how internal audit teams can structure AI-supported documentation around defined inputs, non-fabrication rules, clarification triggers, sampling discipline, and human review expectations.
