Hi, I'm Kelian.
I'm learning to build and keep cloud infrastructure secure.

Computer engineering apprentice at Exxelia, building hands-on skills across AWS and Azure: IAM, infrastructure as code, and secure deployments. I learn fast, ship real projects, and care about doing things properly.

4/5 Apprenticeship year
2+ Cloud projects

About

I'm a computer engineering apprentice at Exxelia, where I work on CI/CD pipelines, internal applications, and IT infrastructure. That hands-on exposure to production systems is what pushed me toward security. I'm building toward a Cloud Security Engineer role, working across AWS and Azure rather than locking into a single provider.

  • Working on: hands-on cloud security projects and lab write-ups, published as they're completed.
  • Learning: AWS and Azure security services, Terraform, and infrastructure hardening.
  • Open to: internships in cloud security, and conversations with people in the field.
  • Ask me about: cloud infrastructure, IAM design, or DevSecOps pipelines.
  • Beyond engineering: board member of CESI Nancy's student sports association (BDS), coordinating between school leadership and sports clubs.
