About
Solution architect with over 15 years of experience in designing and implementing cloud systems, DevOps platforms, and software architectures.
I support companies from architecture definition to production, with a pragmatic and hands-on approach.
My strength lies in my ability to intervene across the entire value chain: architecture, development, cloud, automation, and industrialization.
I can design an end-to-end solution, from the backend to cloud operations, including software architecture, DevOps platforms, and industrialization. I also have experience in IoT, from electronics to connected object cloud integration.
What I bring
I work on projects that require both an architectural vision and operational technical expertise.
My goal is to transform business needs into solutions that are:
- robust
- maintainable
- scalable
- secure
- industrialized
Unlike a purely theoretical approach, I remain involved in technical choices, proof of concepts, critical component development, and team support.
