Complex Systems Architect – Cloud · Data · Security · Compliance

Independent consultant with over 20 years of experience, I support companies in the design, security, and transformation of critical systems under strong operational, regulatory, and security constraints.

I mainly work in high-criticality environments (banking, energy, transport, public sector) to define sustainable architectures, arbitrate structuring choices, and ensure the reliability of large-scale cloud and data platforms.

Areas of expertise:

• Cloud & Hybrid Architectures (AWS, Azure, GCP, IBM Cloud)

• Data & Streaming Platforms (Data Lake, Kafka, Flink, Druid…)

• Cybersecurity & Compliance (governance, audits, hardening, cloud security)

• Distributed Architectures and Resilience

What I bring:

• Clear and pragmatic architectural vision

• Technical decisions in complex contexts

• Security integrated from the design phase

• Support for technical teams and decision-makers

I work as an independent consultant or in collaboration with consulting firms on high-stakes architectural missions.
