Back to original languageAbout Jocelyn
Most cloud architectures are impeccable on paper, then break in production due to security, cost, or scaling issues.
I help companies design and deploy secure, production-ready cloud platforms on AWS, Azure, and GCP. I also support the adoption of AI (RAG, autonomous agents) without exposing company data. Access control, auditability, and cost management are considered from the start, not added as an afterthought.
What I do:
- Secure and highly available cloud architecture (AWS Landing Zone)
- Production AI adoption with data protection
- Security audit and consulting
- DevOps, Infrastructure as Code (Terraform), FinOps
- Tech lead and team cloud adoption
Over 20 years in IT, including 16 in the cloud, in demanding environments within aerospace, public sector, healthcare, insurance, and energy.

Certified TOGAF, security by design.
Have a cloud project that needs to scale, remain secure, and perform in production? Let's discuss, I respond quickly.
