Senior🎓
Top SchoolGuilhem Castillo is a cloud security and AWS specialist with 10 years of experience modernizing infrastructure for large, regulated organizations across finance and technology. Currently a Principal Advisor at CDPQ, he has secured and governed 200+ AWS accounts by building IaC-driven security frameworks and serverless automation that enforce continuous compliance. His background blends deep hands-on skills—Terraform, Kubernetes, Ansible, Packer—and platform governance with a strong track record in migrations, training, and embedding security into DevOps practices. Notable for bringing enterprise-grade controls to highly regulated environments (Deutsche Börse, Barclays, National Bank), he pairs practitioner-level troubleshooting from his Linux/UNIX roots with strategic risk reduction. Colleagues rely on him for pragmatic, repeatable cloud patterns that scale across teams and accounts.
