What I'm looking for

I’m looking for remote or on-site roles where I can optimize SAP FI billing and AR/AP, automate invoice and payment workflows, and deliver measurable improvements with strong stakeholder collaboration and Power BI reporting—ideally in Uruguay or Chile.

I’m a bilingual Financial Operations & Billing Specialist with 8+ years of experience in billing, accounts receivable (AR), accounts payable (AP), payment processing, and financial controls in multinational renewable energy environments. I bring deep expertise in SAP FI and end-to-end process automation in high-volume operations.

At Statkraft Chile, I resolved payment chain bottlenecks, cutting processing time by 95% (from days to minutes) and reducing reliance on external consultants. I mapped critical market operations processes, improved reporting and response times by 50%, and led SAP integration with the invoice portal to automate processing of 500+ invoices daily—eliminating manual entry.

I also built and maintained Power BI dashboards for KPI reporting with 100% on-time accuracy across 12 consecutive months, and I drove measurable performance improvements such as decreasing non-conformities by 85% and resolution time by 60% in under 12 months. I replace brittle RPA approaches with stable integrations (SFTP/XML), own process accuracy through rigorous data mapping validation, and focus on sustainable, Lean-style operational improvements.
