About Cyril

Senior DevOps & Infrastructure Engineer | 25 Years in IT | Banking & Critical Systems Expert

I'm a senior infrastructure and DevOps engineer with 25 years of experience, including nearly 8 years specializing in core banking platforms (OLYMPIC at ERI Bancaire SA, Geneva). I help companies modernize, automate, and secure their IT operations — from legacy application containerization to full Kubernetes-based infrastructure

What I can do for you:

🔧 Infrastructure as Code — Terraform, Ansible, and Kubernetes deployments on VMware vSphere. I design and build production-grade clusters (Harbor, Rancher) and automate infrastructure provisioning end-to-end

📊 Monitoring & Observability — Quick-turnaround setup of ELK stack, Nagios, or Prometheus/Grafana dashboards. Many businesses run with zero or minimal monitoring — I can get you a working setup with clear visibility in 1-2 days

🐳 Legacy Application Containerization — Rare expertise: I've containerized COBOL/Tomcat-based legacy systems for multi-cloud deployment (AWS, Azure, OpenShift) in a regulated banking environment. If you have legacy apps that need to move to containers, I know how to do it properly

⚙️ CI/CD Pipelines — GitLab CI/CD pipeline design and automation, from build to production deployment, with a strong focus on reliability and repeatability

🖥️ Scripting & Automation — Bash, Python, and PowerShell automation for reporting, deployment, and operational tasks across Linux and Windows environments

Why work with me
25 years of hands-on IT experience across banking, HPC, telecom, and datacenter operations
Currently pursuing CKA and KCNA certifications (Kubestronaut track)
Comfortable working independently with minimal onboarding — I move fast and document everything
Available for short missions (audits, setup, automation)
Based near Geneva available on-site or fully remote
Contact me if you need quick infrastructure audit, monitoring setup or help with performance issues
