What I'm looking for

I'm looking to contribute legal operations, billing, claims, or case-management experience in an international, structured environment where accuracy, compliance, process coordination, and cross-functional collaboration matter.

I've supported international legal operations through billing, claims administration, and case management in high-volume, deadline-driven environments.

At Dannemann Siemsen, I reviewed legal service records, prepared complex billing drafts using multi-jurisdictional case data, and corrected discrepancies across systems. I worked closely with legal and finance teams to meet client-specific billing rules and monthly deadlines.

At Costa Fernandes Advogados, I structured legal and claims data, managed case intake, reviewed decisions for financial obligations, and tracked claims, payments, and case progression. I also coordinated with courts and external institutions to resolve outstanding issues.

I'm currently building my Business English skills in Ireland while bringing a detail-focused approach to documentation, compliance, process coordination, and reliable administrative support.
