About Me
Site Reliability Engineering
I'm a site reliability engineer, focused on cloud-native deployments and infrastructure as code (IaC). I am most familiar with the Kubernetes ecosystem on bare-metal.
In terms of professional experience, I have worked on large on-premise Kubernetes fleets for SpaceX's Starlink ISP.
I am a
- Certified Kubernetes Security Specialist (LF-24hswd9rmm)
- Certified Kubernetes Administrator (LF-inn96e0qrb)
- Red Hat Certified System Administrator (180-132-714)
Software Engineering
I'm a developer focused in Object-Oriented Programming and Backend Systems Development.
In terms of professional experience, I have worked on very large scale backend systems, both at Google and Amazon.
I am most familiar with the Java, C, Python, and GoLang languages. I also have some limited experience in C++, C#, JavaScript, and Scala.

Projects
Homelab IaC — a fully HA k8s deployment using Terraform and Flux
Kubernetes YAML, Terraform, NixStarting from minimal working Proxmox and Ceph clusters, this project uses pure Terraform to bootstrap NixOS nodes and install a full high availability (HA) deployment of Kubernetes.
Following k3s bootstrapping, the project uses Flux gitops to deploy all the Kubernetes workloads in the cluster, including automatic secrets encryption/decryption with Mozilla SOPS.
Both geraldwu.com and wuhoo.xyz (and all related services) are hosted on this Kubernetes cluster.
Uptime.rs — A simple, statically generated uptime monitoring application
Rust, GoA simple, self-hostable uptime monitoring service written in Rust. It scrapes a list of websites and regenerates a static status page every minute. I wrote this because I felt all existing monitoring solutions were too bloated (JavaScript, dynamic page generation), and also not configurable as code. Uptimers is entirely configurable through a single YAML file.
It integrates with the Go shoutrrr notification library through C FFI to provide notifications when a site goes down.
Adbir — Another dashboard but in Rust
RustA dashboard webUI inspired by Homer, both in design and configuration.
While I enjoy the configurability and relatively minimalist design of Homer, I dislike its hard dependency on JavaScript to render the page. This is a stripped down rewrite of Homer without any JavaScript.
