name: Satyajit Barik
role: Senior DevOps Engineer
location: India 🇮🇳
experience: "3+ years production-grade infrastructure"
focus:
- Kubernetes cluster engineering (kubeadm)
- Cloud migrations & workload portability
- Infrastructure as Code (Terraform)
- CI/CD automation & GitOps
- Storage engineering (Ceph · Linstor · DRBD)
currently:
building: "Production K8s clusters on Utho Cloud"
migrating: "Azure → Utho Cloud workloads"
automating: "Everything that can be automated"
philosophy: "Reliability is a feature. Automation is the product."|
Azure → Utho Cloud Production Kubernetes workload migration with zero-downtime cutover, optimized storage via Linstor, and GitOps-driven deployment pipeline.
|
Multi-Cloud Infrastructure Reusable, versioned Terraform modules for provisioning VPCs, subnets, security groups, and managed services across Azure, AWS, and Utho Cloud.
|
|
S3-Compatible at Scale Self-hosted S3-compatible object storage layer integrated with Kubernetes workloads, handling production traffic with high durability.
|
End-to-End Automation Jenkins → Container Registry → ArgoCD deployment pipeline with automated rollbacks, health checks, and Slack alerting.
