  • GNU/Linux system professional with particular high level of empathy and social skills knowledge  built in the last 9years. Very effective in being a Capability Enabler, following organizations during internal restructuring as mediator, coach and Infrastructure Architect. With overall 26+ years of market experience.
  • I have been passionate about sailing since childhood and attempting to become a sailing instructor at the Centro Velico di Caprera. Together with Les Glenans and the german DHH, CVC is one of the oldest sailing schools in Europe and it is run by volunteers. I also love skiing and cooking.
  • I embraced the Cloud Native revolution as early as 2016. I am a fan of Kubernetes, Traefik (and I submitted patches) +DataDog, ArgoCD and SealedSecrets. Together with the team at ClovrLabs we established stacks as blueprints for each product that we spawned.
