Hi, I'm Rafał.
I'm a Staff Engineer at Livepeer, specializing in Golang, Blockchain, Kubernetes, and Cloud.
I take projects from 0 to 1 - shaping ideas into solid, scalable, and well-maintainable systems.
Over the years, I've honed my skills at organizations like Google, CERN, and Hazelcast.
I enjoy sharing what I learn - I’ve spoken at over 70 tech conferences (including KubeCon, twice),
written numerous blog posts, and authored a few books.
On a more personal note, I love running and mountaineering.
