Back to original languageAbout Benjamin
Graduated engineer from Mines Télécom.
Voltaire certified at business level (2015).
I prefer simple solutions to complex problems, rather than complex solutions to simple problems.
I am fond of roles requiring versatility and optimization.
I know how to adapt to different contexts, different missions, and different audiences. I like to share, learn from others, teach others, and learn with others.
I am particularly comfortable:
- with Infrastructure as Code technologies (Ansible, Terraform)
- with Linux environments
- with microservices environments (Docker, Kubernetes)
- with writing CI/CD pipelines
