Production CI/CD overhaul (Toontown)

Worked with a small team to rewrite a previously manual deployment system, such that we are now able to publish client and server game updates via code merge and a few clicks. We used GitLab CI as our CI platform to publish client patches and containerize server updates, and declared our Kubernetes infrastructure (ingresses, services, policies, etc.) in a Helm chart.

Vega - Script output framework

Vega was a really quick project to solve the problem that I had of checking a bunch of different websites at once for a few pieces of information. Instead, I can set up a series of tasks to run on a schedule, and dump the information I need to HTML.

Steakscorp - Custom-built development server

Steakscorp was originally a (hardware) system building project I completed in the summer before my senior year of high school. It is still in very active use today and runs many services, such as gaming servers (Minecraft, Team Fortress 2, Garry's Mod), VoIP servers (Mumble, TeamSpeak), database servers (MySQL, MongoDB), and web servers (Apache2, Node.js), as well as being a development and testing server for many of my web and non-web projects.
