My name is Honza Dvorsky and I’m a Senior Software Engineer at Apple. Previously, I studied MSc in Advanced Computing at King’s College London, BSc Robotics at CTU Prague, created a few open source projects and helped build SwiftKey for iOS.

I swim, play basketball, travel, and write on topics ranging from technology to climate change, social justice, and human rights – and how they all interact.
