About Julien

As an energetic and empathetic Strategic Data Consultant, I specialize in designing and implementing enterprise data architectures, analytics solutions, and governance frameworks. I bring deep expertise in data modeling, policy development, and process design—always with a pragmatic, business-oriented mindset suited for complex and politically sensitive environments. My approach is grounded in an organization’s data maturity, strategic priorities, and domain-specific context.

With a robust background in both data architecture and process optimization, I bridge the gap between business and technology by translating complex requirements into practical, sustainable solutions. I’m known for my ability to clearly communicate data-related topics, guide diverse teams, and deliver tangible results through structured collaboration.

I work fluently with leading standards and frameworks such as DAMA-DMBOK, TOGAF, GDPR, ArchiMate, and Zachman. My designs are platform-independent and built for scalability, consistency, and long-term value across various domains.
