Onchain Game Engineer · Cairo · Starknet · Dojo
Former mechanical engineer, now building games whose rules, and physics, can be proven.
At Cartridge, I build the gaming infrastructure of Starknet. In open source, I'm porting reputable Rust crates to Cairo, so that whole games, physics included, can be proven and settled on Starknet. Each package is measured in gas from day one and published on scarbs.xyz.
| Package | Port of | Highlight |
|---|---|---|
fixed |
f64 |
Q32.32 fixed point, bit-exact, loop-free trigonometry |
simba |
simba | Scalar traits for generic linear algebra |
nalgebra |
nalgebra | 99.9 % of the API (1,885 of 1,886 items), up to SVD and eigen decompositions |
glam |
glam | 7 to 12× less gas than a cubit-style scalar on vectors, matrices and quaternions |
glamx |
glamx | Rotations, poses and symmetric matrices for physics |
rapier2d |
Rapier | Rigid bodies, colliders, joints, events, world save and restore |
hexx |
hexx | Hexagonal grids, with boards stored as bitmaps in a single felt |
quiver |
Arcade | Quests and achievements as native Starknet components |
They power my games: Slingfall, a provable slingshot game on Sepolia, and Grim World, a fully onchain tick-based RPG.
