๐Ÿ‘‹ Hi, Iโ€™m Tim Heverin

๐Ÿ’ป Senior Systems Engineer | Cloud & Automation | Identity | DevOps

I design and support enterprise IT and homelab environments focused on automation, cloud infrastructure, and identity.
My work blends hands-on systems engineering with modern DevOps practices leveraging PowerShell, Terraform, and GitOps to improve efficiency, reliability, and security across hybrid environments.


๐Ÿ”ง Technical Focus

  • Automation & IaC โ†’ PowerShell, Python, Bash, Terraform, GitOps (ArgoCD)
  • Identity & Access โ†’ Active Directory, Entra ID, Okta, Authentik SSO
  • Cloud & Infrastructure โ†’ Azure, AWS, VMware vSphere (HA/DR), Docker, Kubernetes (K3s)
  • Security & Hardening โ†’ Intune baselines, Conditional Access, Defender for Endpoint, Tenable remediation
  • Monitoring & Observability โ†’ Grafana, Prometheus, Loki, ELK Stack, Blackbox Exporter

๐Ÿ—บ๏ธ Homelab Architecture

๐Ÿ“Œ Featured Projects

  • PowerShell Playbook โ€” Enterprise automation toolkit with PowerShell modules for identity governance, auditing, and system reporting.
    Focused on improving maintainability, patching workflows, and service reliability across Windows environments.

  • single-vm-gitops-homelab โ€” Fully automated GitOps homelab built on Docker, Prometheus, and reverse proxy stacks โ€” all managed through Terraform and CI/CD.

  • homelab-sso โ€” Identity & Access sandbox demonstrating Authentik SSO integrations for apps like Portainer and Grafana using OAuth2/OIDC.

  • monitoring-stack โ€” โ€œObservability in a Boxโ€ โ€” Grafana + Prometheus + Loki + exporters, with alerting, dashboards, and self-healing watchdog scripts.

  • CafeOps โ€” A whimsical AWS + LocalStack serverless project combining Terraform, Lambda, and API Gateway โ€” proving even coffee deserves CI/CD โ˜•.

  • deepdish-cluster โ€” K3s cluster built via Terraform showcasing hybrid Kubernetes automation and cluster bootstrapping.


๐ŸŽฏ Current Goals

  • Expanding automation blueprints for hybrid infrastructure
  • Enhancing cloud-native designs using AWS & Terraform
  • Studying for the AWS Certified Solutions Architect โ€“ Associate exam
  • Continuing to evolve the homelab into a full GitOps platform
