I am Nathan Guerrero, a tinkerer and software developer, focused on DevOps and the back-end. At the moment, I am looking for work! (Remote or in-office)

I am strongly proficient in Python, C/C++, and Java, with experience across the stack, from React to SQL. As for DevOps, I am knowledgeable in Docker, Nix, and Ansible (for IaC), CI/CD pipelines (with GitHub Actions), and shell scripting (e.g. Bash).

Currently based in San Diego, CA, having graduated from the University of California, Irvine in 2025, with a B.S. in Computer Science.

Much of my time is spent on the Sapphic Homelab/Home Server, a continuously-evolving cluster of repurposed machines running Proxmox (and TrueNAS SCALE). They host many NixOS-based VMs and Docker-based container workloads (with Docker Compose and Komodo), supported with many layers of CI/CD pipelines and orchestration. Services hosted include Pterodactyl, Immich, and n8n, all connected together with Traefik and Tailscale. Here is a video demonstration (uploaded 2026/09/29)!

As well, I daily drive Arch Linux, with my dotfiles and other configuration in linux-config.

• saphnet-nixos-configs, my NixOS flakes for my VMs
• saphnet-compose-configs, my Docker Compose stacks for my services, plumbing included (through Komodo Resource Syncs)
• saphnet-komodo, my main Resource Sync for Komodo
• saphnet-ansible-playbook, my Ansible playbooks for node deployment automation
• saphnet-homepage, a multi-application Docker image serving a highly customized Homepage instance
• saphnet-sftp, a custom Docker image for simplified SFTP servers
• saphnet-nginx, a custom Docker image for simplified reverse proxy setups with Nginx
• saphnet-pterodactyl-images, a set of custom Docker images for Pterodactyl
• nixos-cloud-init-installer, a NixOS image/flake for flexible cloud-init provisioning, built with GitHub Actions
• docker-volume-rclone, a custom Docker image for syncing Docker volumes to a remote location on a schedule
• certbot-dns-namecheap, a fork of the original certbot-dns-namecheap with an automated CI/CD setup for Docker images
• renovate-config, a set of Renovate presets shared between the above repositories, with custom functionality
