I build open-source tools, games, and simulations — and share the journey with everyone who comes along.
About
Hi, I’m Daniel.
I’m a software engineer based in Denver, CO, and the founder of Preponderous Software and Dan’s Plugins Community. For years I’ve been building open-source tools, games, and simulations — driven by curiosity and a genuine love for sharing what I make with others.
By day I work on edge AI and operational infrastructure at EdgescaleAI. Outside of work I create: Minecraft plugins running on hundreds of servers worldwide, Unity games with procedural generation, and agentic AI experiments using the Anthropic API. Everything I build is on GitHub.
Featured Projects
A selection of the things I’ve built and shipped.
A self-hosted, Discord-like real-time chat application with multiple channels, WebSocket messaging, message persistence, and both a browser interface and a LibGDX desktop client. Deployed with Docker Compose.
The org site for Dan's Plugins Community, my Minecraft plugin persona — a showcase of the plugins I maintain, including Medieval Factions and Wild Pets.
A lightweight Python graphics library built on pygame that provides simple, reusable methods for graphics programming. MIT licensed and used as a dependency in other projects such as Roam.
A Minecraft plugin that lets players simulate sovereign nations — creating factions, claiming territory, waging war or diplomacy, writing laws, and holding dueling tournaments. One of the most mature, community-driven projects in the portfolio.
A community-agnostic, Docker-based Minecraft server infrastructure with a Spring Boot dashboard, automated backups, Discord alerts, RCON support, and a full CI/CD pipeline. Configurable via environment variables.
The org site for Preponderous Software, my game-dev persona — home base for Roam, Barony, Microbiome, and other games and simulations.
A single-player 2D sandbox game where you explore a procedurally generated world, gather resources, and interact with your surroundings. Built with Python and pygame using the graphik library.
A foundational spatial simulation service that manages environments, grids, locations, and entities via a clean REST API. A reusable backend for simulation games, AI experiments, and virtual worlds.
An open-source Minecraft plugin that lets players tame any entity in the game. Originally created in response to a player's request to tame foxes. Available on SpigotMC.
