Über Isaac
Senior DevOps/SRE Consultant and Tech Lead with 10+ years designing, building, and operating cloud infrastructure. For the past 5 years I've led infrastructure teams — defining technical roadmaps, making architecture decisions, and acting as the go-to person for infrastructure across the engineering organization.
I combine strategic thinking with hands-on execution — from planning the roadmap to writing the Terraform.
AWS at scale: Multi-account architectures (Organizations, Transit Gateway), multi-region DR (active-passive), IRSA, cost optimization with Karpenter, Spot and Savings Plans.
Kubernetes: Production EKS clusters (50+ nodes, 50+ microservices), on-prem K8s with Kubespray, Istio, custom Helm charts, Karpenter, cert-manager, external-dns.
GitOps & CI/CD: ArgoCD, GitLab CI, Bitbucket, reusable Terraform modules across multi-account setups.
Observability: Prometheus, Grafana, Loki, ELK, Jaeger, OpenTelemetry in production. SLOs agreed with business, blameless postmortems, structured on-call rotations.
Security & compliance: Vault, AWS Secrets Manager, image scanning in CI/CD, network policies, pod security. ISO 27001 audit experience.
Available for remote engagements — part-time, project-based, or ongoing advisory.
