I build multiplayer games from prototype to live operation.

At XOX Studio, I helped build and maintain a game portfolio that peaked at roughly 25,000 concurrent players. My work spans gameplay systems, exploit prevention, live updates, and coordinating developers.

Programming, production, and the team behind the game

I learned development by fixing things I did not yet understand. At fourteen, that meant broken MTA roleplay servers, unfamiliar Lua, and a lot of searching through other people’s code until the errors made sense.

That habit stayed with me. At XOX I went from building early games largely alone to coordinating people and maintaining live titles that reached roughly 25,000 concurrent players. The job has included programming, UI, models, exploit fixes, live updates, and the less visible work of deciding what is worth building next.

I still want to make original, story-led games. The hardware, Linux, Unity/Godot, shader, and local-AI experiments elsewhere on this page are how I keep learning outside the demands of a live studio.

Things I built to understand them

Compatibility runtimes, gameplay prototypes, and hardware projects that extend my work in multiplayer systems.

In development / Systems programming

M32 — Intel Mac compatibility runtime

I’m building M32, a compatibility runtime that brings 32-bit Intel Mac applications to Apple Silicon. It loads and executes original macOS binaries, translating their system and graphics calls into native functionality.

Unity & Godot prototypes

Gameplay prototypes and GLSL shader experiments exploring rendering and engine behavior.

GTA modding

MTA and SA-MP were my first real classrooms: unfamiliar Lua, broken roleplay systems, memory hooks, and fixes found by reading until the system stopped being mysterious.

03 / constrained hardware

ESP32 and RP2040

Displays, telemetry, and C++ drivers where memory and timing limits make every unnecessary layer visible.

C++ / SPI / I²C
04 / odd devices

Embedded Linux

ARM tablets, touch interfaces, custom configurations, and the satisfaction of making hardware useful beyond its intended life.

Local AI tooling

Ollama, MCP integrations, and small automations that help with development without sending every task to a hosted service.
