Back to original languageAbout Abdelkarim
Architect & SAP Integration Lead | Data | AI
I design and manage integration architectures that hold together critical enterprise systems — seamlessly, incident-free, and on schedule.
For over 10 years, I've worked on complex programs (ERP, middleware, AI, 5G, embedded systems) for major groups like **VINCI Construction, Engie, Nokia, Valeo, Bosch**, and **Renault**. My approach is straightforward: I understand both business needs and technical depth, which allows me to avoid costly architectural errors early on.
What I bring concretely:
On SAP projects (S/4HANA, BTP, Integration Suite / CPI, Ariba, MDG, DataSphere), I handle the target architecture design, end-to-end flow governance, and oversight of build teams through to go-live. Notably, I led SAP integration at Engie as part of the GET program, across Europe.
Beyond SAP, my background covers software architecture, embedded systems (Nokia, Bosch, Valeo), and data/AI (NLP, Deep Learning, Azure AI) — giving me a rare systems perspective in pure integration roles.
For whom?CIOs, PMOs, Business Leaders looking for a profile capable of scoping, arbitrating, and delivering — not just executing.
Available for hybrid (min. 2 days remote work) or full remote, mobile in France & Europe for key phases. Feel free to contact me for a quick discussion about your context.
