Hi, I'm Joshua 👋

Principal Systems Architect & Engineering Lead
Event-driven platforms · Developer infrastructure · Unreal Engine systems

QBCore creator Mantle founder LinkedIn


I've spent 8+ years designing and building developer platforms, runtime systems, and event-driven infrastructure at scale. I'm best known as the creator of QBCore, an open-source multiplayer framework running on thousands of live servers and used by millions of players worldwide. Today I'm building Mantle, a platform for player-made worlds on Unreal Engine 5.

🚀 Featured work

QBCore Framework · Open source

Creator and original architect of the de facto standard framework for multiplayer server infrastructure in its ecosystem.

  • Resource management runtime for loading, isolating, and orchestrating modular server resources
  • Event-driven communication layer connecting server, client, and inter-resource messaging
  • Extensible API framework that lets a large community build and ship on a shared foundation

Mantle · Unreal Engine 5

Founder and sole developer.
Build places in Unreal Engine. Publish them. Play them together.
A platform for player-made worlds built on Unreal Engine 5. Creators build places in the Unreal Editor, publish them to Mantle, and players join through the Mantle client.

  • MantleCore: public UE 5.8 authoring plugin to build, check, upload, and Test locally in the real client
  • Multi-language scripting: gameplay in Luau, TypeScript, or Python against a single Mantle API, plus a visual graph editor
  • Community hosting: creators can run their own Linux or Windows servers for their places

🧠 What I focus on

  • Architecting event-driven systems and platform APIs that other developers build on
  • Developer experience: tooling, extensibility, and frameworks that scale with their communities
  • Real-time and game runtime systems, including Unreal Engine

🛠️ Languages & tools

JavaScript TypeScript Lua C++ Node.js Vue.js Unreal Engine
