What I do
Engineering and project coordination, with equal weight.
Pilots & architecture
I turn partner requirements into working cloud-edge pilots, from continuous certification for a bank to an industrial data-space platform.
See the work →EU project delivery
I own tasks, pilots and deliverables in Horizon Europe, CDTI and IPCEI-CIS projects, and represent OpenNebula at reviews and General Assemblies.
See my projects →Sovereign AI infrastructure
I deliver AI services on European clouds, like EuroCopilot across 9 availability zones on 5 providers, and contribute to EuroHPC AI Factory work.
