Back to original languageAbout Maximilien
Technical Architect SAP, with over 20 years of experience. Dual expertise: architect of several complete greenfield S/4HANA implementations (on-prem and Private Cloud), and principal architect/developer of a GenAI solution on SAP BTP that automatically analyzes and documents SAP custom code. SAP certified, published on the SAP Store, in production with about ten clients.
Developer turned architect, remaining hands-on across the entire chain: backend (ABAP, SAP RAP), frontend (Fiori, SAPUI5), integration (BTP Integration Suite), and architecture. This allows me to deliver realistic architectures and reliable WRICEF estimates.
Pragmatic rather than dogmatic: when faced with a real technical trade-off, I present the options and their compromises, with the sole criterion being the project's success.
Available to discuss your needs. I will gladly provide more details, with references to support them.
