Descripción

I’m a SAP FICA and BRIM CI specialist with a hybrid background: deep functional expertise paired with strong ABAP development skills. This combination helps me diagnose issues quickly, design cleaner solutions and bridge the gap between business, functional and technical teams.

I’ve worked extensively with S/4HANA systems, supporting clients in the utilities, telecommunications and retail sectors across full project lifecycles. My experience covers requirements analysis, solution design, configuration, development, testing, data migration and incident management. I’m particularly strong in FICA processes, BRIM Convergent Invoicing, FI integration and ABAP coding.

I’m known for identifying root-cause issues and proposing practical, scalable solutions. Highlights include:

• Designing a process to de-archive written-off invoices, cancel them and regenerate clean postings.

• Detecting and resolving a batch error that deleted a month of payment data, enabling full recovery.

• Leading end-to-end FICA data migration for a complex brownfield S/4HANA implementation.

• Re-implementing and optimizing dunning, payments and payment plans for a client with extensive custom code.

My goal in every engagement is simple: deliver stable, efficient and maintainable SAP solutions. With a 360° view of processes, system architecture and S/4HANA capabilities, I help organizations reduce complexity, increase reliability and accelerate delivery through smarter design.

Spanish native, fluent in English.

Open to SAP FICA, BRIM CI, FI and ABAP opportunities—across functional, technical or solution architecture roles.
