Role & scope

Solo, end to end — game engine, AI, multiplayer, and deployment are all one person's build.

Project entry

Moves

• Build the Pitch

  Built the full 3D match engine in React Three Fiber and Three.js, from charge-based shooting and lofted passes to goalkeeper dive animations.

• Teach the AI

  Gave defenders and goalkeepers formation-aware tactical behavior, not just ball-chasing.

• Go Multiplayer

  Wired up real-time 1v1 matches over Supabase Realtime, on top of the same single-player engine.

• Ship Multiple Modes

  Full 11v11 matches, standalone penalty shootouts, and free-kick practice, all live and playable, not a tech demo.

Outcome

A genuinely playable, publicly deployed 3D football game with 260+ commits of active development.
