Experience

Minecraft Server

https://github.com/sbezboro/standard-web-flask

Developed an entire ecosystem for a Minecraft server I ran for about seven years, with a Python/Flask-based website, various Java plugins, and a Node.js real-time streaming server for live chat to/from the site and ingame. The server was decently popular in its heyday, with up to 100 players online at a time.

MCRunner

MCRunner is a client/server system that allows the control and monitoring of multiple Minecraft server instances on a single machine. It is based on the Supervisor process control system, something I've had a lot of experience with. The repo has 100% line and branch coverage, and full documentation.
