About Charles

I am a senior functional SAP consultant with over twenty years of experience, specializing in logistics and finance domains on ECC and S/4 HANA.
For several years, I have been involved in S/4 HANA projects in Retail and dematerialization, particularly in procurement for La Redoute, Solocal, Editis, and Vinci Construction. My role covers functional design, configuration, and complete integration of incoming and outgoing invoice flows, including electronic interfaces and control automation.
I am recognized for my ability to quickly understand business needs, design robust solutions, and deliver autonomously.
As a freelancer, I am independent, comfortable interacting with both IT teams and business users, and I work in both Build and Run phases.
