I am Robin Pokorny, a zealous JavaScript Engineer based in Berlin.

Currently working at NewStore, creating a mobile retail platform in React. I enjoy writing functional JavaScript, explore Reason for inspiration.
Having a Maths degree, I relish both complex tasks and clean solutions. To share the fun I organise meetups, record coding videos, and frequently speak.
