Callo, Roblox game developer & Luau scripter

I build the systems that make Roblox games feel good to play — gameplay, cutscenes, UI, physics and networking that hold up at scale.

What I do

Technical implementation,
end to end

  1. Game systems

    Core loops, progression, inventories and economies built to be extended.

  2. Cutscenes

    Camera work and scripted sequences that sync across every client.

  3. UI

    Responsive interfaces that work on phone, console and desktop.

  4. Physics

    Vehicles, ships, constraints and anything that has to move convincingly.

  5. Networking

    Server-authoritative code with remotes that are validated and lean.

  6. Performance

    Profiling and fixing the frame drops and memory leaks players notice.

About

About me

I'm a UK-based scripter focused on technical implementation. I like turning a design doc into something that runs smoothly for millions of players — clean Luau, careful networking and performance that doesn't fall over on a full server.
