About this author
Matyas Rathonyi is a 19-year-old student and indie developer from Hungary, and the founder of Clamshell, the app that keeps a MacBook and its AI agents working with the lid closed. His background is in 3D animation: he spent years in Blender before Clamshell, which became his first shipped product. He designs and builds it on his own, working alongside AI coding agents, and writes guides at clamshell.dev on keeping a Mac awake for long-running work.
