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

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

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 homelabbing/self-hosting, shown in the Sapphic Homelab/Home Server, a cluster of repurposed machines running Proxmox and TrueNAS SCALE. They host many NixOS/Linux-based virtual machines and Docker-based containers (with Docker Compose and Komodo), supported with CI/CD pipelines and automation scripts. Services hosted include Home Assistant, Pterodactyl (a game host), and a Linux-based development server, all connected together with Traefik and Tailscale. Here is a video demonstration!

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 numerous services
• saphnet-ansible-playbook, my Ansible playbooks for automating the deployment of various nodes
• saphnet-sftp, a custom Docker image for simplified SFTP servers
• saphnet-nginx, a custom Docker image for simplified reverse proxy setups with Nginx
• nixos-cloud-init-installer, a NixOS image/flake intended for flexible cloud-init provisioning, built with GitHub Actions
• docker-volume-rclone, a custom Docker image for synchronizing 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 creating Docker images
