I'm Ricardo Antonio (aka ricodevvv). I live in Hidalgo, where I build the future.

I write server software for Minecraft. Not maps, not builds — the layer
underneath: a PaperSpigot fork with its own knockback and packet APIs, a
packet-level anticheat, a practice core running ten minigames, a replay system
that records matches and plays them back.

Most of it is Java. Some of it is 1.8.8 and Java 8 because that's where
competitive PvP still lives, and some of it is Java 21 with MongoDB, MinIO and
zstd because storing thousands of replays is a storage problem before it's a
Minecraft problem. Working across both ends has been the most useful thing about
this niche: you learn NMS internals and distributed storage in the same project.

I care about the parts nobody demos. Knockback that feels identical on every
server in the network. An anticheat that flags a real cheater and not a player on
a bad connection. A kit format someone else can edit without opening an IDE.
That's the work.

Outside of Minecraft I build with Next.js and TypeScript — this site included.
