What I'm looking for

I’m looking for a role where I can lead indirect tax transformation in Brazil—combining ICMS/DIFAL/PIS/COFINS expertise with tax technology, analytics, and automation to deliver audit-ready compliance, tax reform simulations, and scalable governance.

I bring 13 years of experience in indirect taxation, customs and trade, and tax technology—working at the intersection of Brazilian tax law (ICMS, DIFAL, PIS/COFINS, IPI, ISS) and the Brazilian Tax Reform (dual VAT through IBS and CBS, selective excise tax / IS, cClassTrib taxonomy).

In my current role, I lead Brazilian indirect tax compliance and technical oversight on electronic invoicing (NF-e), CFOP/CST/cClassTrib, and fiscal parametrization, while driving Tax Reform readiness under Complementary Law 214/2025 and Decree 12,955/2026. I design and run IBS/CBS simulations using a proprietary Python application, maintain an audit-ready Power BI compliance dashboard, and use generative AI agents to reduce regulatory response lead time from days to hours. I also own an auditable NFCF workflow (SharePoint, Power Automate, Microsoft Forms) that strengthens fiscal document governance and traceability.

Previously, I operationalized the New Import Process (NPI/DUIMP) within Siscomex, maintained strong catalog compliance, and built dashboards that translate customs data into actionable strategy. Earlier at KPMG, I delivered indirect tax and customs advisory, leading NCM/HS classification reviews and due diligence across 1,000+ SKUs, and supported special customs regimes, valuation, rules of origin, and compliance for multinational expansion in Brazil and Mercosur.
