"Never stop learning."

I'm a Linux systems engineer and developer with a strong passion for automation, back-end tooling, and infrastructure.

I specialize in:

• Writing minimal, functional, dependency-free Bash scripts, and (if I must) POSIX shell scripts
• Building infrastructure as code (IaC) and configuration as code (CaC) with Ansible
• Managing servers and self-hosted services in my homelab (Proxmox + K8s)
• Documenting everything using Markdown/MkDocs and GitHub Pages
• Implementing CI/CD pipelines using GitHub Actions

I'm currently working towards a career in DevOps/Platform Engineering, and I love helping others learn the command line and Linux systems from the ground up.

• Personal Tech Notes Site: MkDocs site with all my notes on various aspects of technology (Bash, Linux internals, cloud, etc.)
• ProLUG Course Sites: Maintainer of open-source Linux courses
• Kubernetes Deployment Scripts: Set of Bash scripts and Ansible playbooks used to configure a highly available K8s cluster
• Proxmox Utility Scripts: Hand-rolled Proxmox helper scripts.
• Automated Monitoring Stack: Ansible playbooks that deploys tools from Grafana Labs (Grafana, Loki, Prometheus, Node_Exporter, Promtail)
• Image Watermarker Application: A Python desktop application used to add logo and text watermarks to images.
• GitHub Backup Tool: Bash script using GitHub API + EC2 + S3 to automate org repo backups (currently private, available upon request)
