FIG. 02.13D & CAD: spur gear, 14 teeth, with a toolpath pass

01

What I work on

Ishan Sahu

At Mira3D I work on MiraPro, our CAD application, and the tooling around it: toolpath generation, computer-vision readers, image search and the licensing and server side. Outside work I build systems from scratch, mostly in Rust: an emulator, a multiplayer game engine, peer-to-peer streaming and Android apps.
