THINGS I'VE BUILT
Projects
Open source tools, plus the Minecraft mods, servers and events I made for some of the biggest Spanish-speaking creators.

open source
WebSocketFabric
Replaces Minecraft's transport layer with WebSockets, so you can put web protection like Cloudflare in front of a server. That shields it from DDoS attacks and cuts packet round-trip times.

Bedrock Proxy
A bridge between Minecraft Bedrock and Java Edition that lets Bedrock players join Java servers, with full Xbox Live authentication.
source code
Minecraft MSA Auth
A Rust library for signing in to Minecraft's online services through Microsoft OAuth2, for building custom launchers and tools.

etheryal kernel
A capability-based operating system kernel written in Rust. Every component shares one address space as a software-isolated process with its own code and data layout, without the cost of task switching. Drivers and user-space apps run sandboxed through WebAssembly (WASI). Inspired by Microsoft's Singularity, it relies on type safety instead of hardware memory protection.

Litecraft
A clean-room Minecraft client written in Rust. I started it at 14, before Rust 1.0 shipped, and other developers joined over time. It was never finished, but it taught me how to build software with other people, and I got to watch the language grow alongside the project.

Elitecraft
A survival SMP where I ran the infrastructure and built optimization and performance mods to keep dozens of simultaneous players running smoothly.
Permadeath
An original event I developed with ElRichMC on Minecraft 1.15.2 in Hardcore, where dying meant a permanent ban. Custom items, abilities, bosses and mobs made survival harder every week until the last player fell.

Saw Minecraft Games
The Saw movies turned into a survival challenge for content creators. I built the core mods and mechanics with realistic physics, like ropes that physically drag players, and managed the servers.

A competitive event where teams of “ants” faced off for victory. I developed its foundational mods.
