Game systems built to scale online

I build gameplay systems, core mechanics and multiplayer architecture for JRPG, FPS and MMO-style games, designed to hold hundreds or thousands of concurrent players.

What I do

From the core loop of a game to the infrastructure that keeps it online.

  1. Gameplay and core mechanics

    Gameplay systems, controllers, combat, progression and the core loops that make a game feel good to play.

  2. Multiplayer and backend

    Scalable online systems with PlayFab, Nakama, AWS or my own infrastructure. Matchmaking, real-time sync, accounts and persistence.

  3. Custom software

    Tailored solutions for companies inside and outside the gaming industry, built to be robust and production-ready.

  4. Infrastructure for prototypes

    Working servers and databases on my own infrastructure for early-stage projects, so you can iterate before moving to the cloud.

Player profile

Robust, scalable, production-ready

Facundo

I focus on scalable online systems for games, integrating and designing backend infrastructure with cloud services or my own servers to keep online environments stable as they grow.

The goal is the same for a video game or any other complex software project: systems that hold up in production.
