About

Professional summary

I am a Business Administrator with extensive experience in accounts receivable, sales administration, credit management, and customer service within large national and multinational companies.

I have managed current accounts, collections, invoicing, customer stock, and credit-risk processes. I focus on reducing collection risk, improving debt aging, and ensuring accurate financial and commercial administration.

I have strong negotiation, commercial, planning, and organizational skills. I work effectively with customers, distributors, sales teams, credit, logistics, and other internal stakeholders.

At Nidera, I coordinated regional current accounts and implemented credit policies that aligned customers and the commercial network with updated standards. I also supported sales operations through systematic customer follow-up and account management.

I have experience with SAP, AS400, BI, and advanced Microsoft Office tools. I was selected as a SAP key user and contributed to the successful implementation and validation of controls to prevent duplicate documents.

Since 2016, I have worked independently, expanding my knowledge of personal finance, long-term stock market investing, and email marketing. I currently support the marketing campaign of a collections company.
