David Brunet

CTO consultant · Fullstack developer · Network & infrastructure architect

Profile

I design, build and operate complete digital platforms, from the initial idea to production. My background runs from telecom field work to cloud native, so I am as comfortable talking network and code as business.

Specialities: robust architectures, Kubernetes, automation, sovereign cloud and integrating AI into secure environments.
