Lex Roller
Founding Engineer at Nori Robotics · YC S26

Building practical robots from first prototype to real-world deployment.

I work across embedded systems, controls, autonomy, product software, and hands-on robot bring-up—turning ambitious hardware into dependable tools people can actually use.
