About Me
Senior Platform Engineer with over 10 years of experience transforming technical infrastructure into a competitive advantage. My primary focus is to eliminate operational friction by creating robust Internal Developer Platforms (IDPs) and APIs that allow product teams to concentrate on what truly matters: code.
Throughout my career in highly demanding technological organizations like CERN and Pictet, I have honed the ability to abstract the complexity of the Cloud and infrastructure through code (IaC) and advanced automation.
How can I bring value to your project?
- Platform and Infrastructure Architecture:Expert in the Kubernetes and Docker ecosystem, with CKAD certification. I design scalable, resilient, and easy-to-operate environments.
- Security and Identity Management (IAM):Specialist in security protocols (OIDC, SAML, OAuth2) and secret management tools like HashiCorp Vault. I have led critical migrations and designed access gateways for thousands of users.
- DevOps Culture & Automation:I develop Terraform modules and CI/CD pipelines that drastically reduce time-to-market. My goal is absolute "self-service" for developers.
- Backend Engineering:Unlike a traditional DevOps profile, I possess a solid background as a software engineer (Java, Python, C#), enabling me to build internal APIs and web services that integrate seamlessly with the company's technological stack.
- Observability and Data:Implementation of monitoring stacks (Prometheus, Grafana, ELK) to ensure the business has full visibility into the health of its applications.
- Global Collaboration:Full professional competence to lead technical meetings, write documentation, and coordinate teams in English and French.
