Back to original languageAbout Yating
Hello, I am Yating Chatiron, a senior DevOps engineer with 16+ years of experience in full-stack engineering and cloud infrastructure. Since 2022, I have specialized in DevOps and architectures for the healthcare sector — an environment where criticality, compliance, and service continuity leave no room for error.
What I do today
Infrastructure as Code | Kubernetes & GitOps | Multi-Cloud (AWS/GCP/Azure)
I design and manage highly available cloud infrastructures for complex healthcare platforms. At Biogroup, I orchestrated a multi-tenant Kubernetes infrastructure supporting 28+ laboratories (20M+ patients) with:
✅ Zero downtime deployments (Blue/Green, GitOps via ArgoCD)
✅ Shift-left security (Prisma Cloud, Trivy, SBOM scanning)
✅ Critical observability (Grafana, RabbitMQ alerting N1/N2/N3)
✅ HDS/ISO27001 compliance throughout the deployment cycle
Core Stack: Kubernetes · Terraform · Helm · ArgoCD · GitHub Actions · Vault · PostgreSQL · Go/Node.js/Python
Why healthcare?
In 2023, I discovered that healthcare is not "just" tech.
Every deployment directly affects doctors, patients, and medical decisions. An incident = a rescheduled surgery, a delayed diagnosis. This responsibility fascinated me — and transformed me.
• 5+ years of e-health experience (Biogroup, ITEKCOM, Livemed’s)
• Deep understanding of the domain (HDS, GDPR, sensitive data, critical SLA)
• Expertise in cross-functional coordination between development, infrastructure, data, and clinical teams
Atypical (but logical) journey

🇺🇸 Boston (5 years) → Full-Stack Engineer (creativity → automation → code)
🇫🇷 France (since 2021) → DevOps + Healthcare Infrastructure
