Technical Expertise

As a senior freelance SRE, my work spans high-volume observability, Kubernetes platform operations, on-prem Proxmox/Ceph infrastructure, and AI-assisted SRE tooling. The stack below reflects what I run in production today, alongside the infrastructure foundations that let me operate confidently across hybrid environments.

  • Observability & Reliability: Grafana, Loki, Thanos, Vector, CloudWatch - SLO-oriented diagnostics and platform hygiene at scale
  • Kubernetes & Platform Operations: Kubernetes administration, Helm charts, Argo CD, container image lifecycle
  • CI/CD & Automation: Jenkins, GitLab CI, GitHub Actions, Terraform, Ansible - delivery workflows that improve safety and repeatability
  • On-prem & Hybrid Infrastructure: Proxmox, Ceph, multi-datacenter HA, virtualization, networking, firewalls
  • AI-Assisted Tooling: Graphia - pragmatic, enterprise-ready AI workflows with guardrails for diagnosis and platform operations
