About

I implement SAP BRIM, specialising in SAP Convergent Charging and its integration with Convergent Invoicing and FI-CA. I also have working knowledge of Subscription Order Management and Convergent Mediation.

I started in telecom billing and charging in 2008 and have worked as a freelance SAP BRIM consultant since 2018.

Today I am SAP BRIM Principal Consultant at Acuiti Labs, where I am also a reporting manager. Before that I led the SAP CC team on a project for a large financial institution. Earlier I worked for Ordina, ran my own consultancy, UKMATA B.V., and contracted for a technology consulting company on a utilities and retail project.
