About Sylvain

Senior Cloud & DevOps Engineer | Design & Migration Infra | 100% Remote

With 20 years of experience in critical infrastructures, I support SMEs, SaaS Vendors, and Mid-sized companies in modernizing and automating their digital assets. My approach is 100% operational: I design and implement solutions tailored to your real needs, prioritizing reliability and cost control.

Examples of results achieved:

Budget Optimization: 50% reduction in infrastructure costs on strategic migration projects (moving from VMware to optimized Cloud/VPS solutions).
Agility (Time-to-Market): Accelerated provisioning, from several weeks to a few hours via Infrastructure as Code (Terraform, Ansible).
Reliability & Availability: 80% reduction in off-hours interventions through architecture simplification and hardening.

My "Hands-on" Expertise:

Target Architecture Design: Analyzing your needs for a performant, secure, and optimized infrastructure (FinOps).
Critical Migrations: Managing and executing your transitions from On-premise to Public Cloud (AWS, Azure) or Sovereign/VPS (OVHcloud, Scaleway, Hetzner).
Industrialization: Full automation via Terraform & Ansible, Docker containerization, and CI/CD pipeline setup.
Support & Mentoring: Technical coaching and customized skills transfer (IaC, Terraform, Ansible, Docker) to empower your teams on their new infrastructures.

Intervention Mode:

Available as a freelancer, 1 to 3 days per week, exclusively 100% remote.
Project & Build Focus: I deliver robust, well-documented, turnkey systems designed for stable autonomous operation.
No On-Call Duty: My role is to build resilient infrastructures that do not require emergency night or weekend support.
