Me

I'm Rafał.

I'm a Golang / Blockchain Engineer working at Livepeer.
I'm also an author of the book "Continuous Delivery with Docker and Jenkins".
From time to time I speak at conferences, write blog posts, and conduct technical trainings.

I specialize in Golang, Blockchain, Kubernetes, Cloud, Java, and Continuous Delivery.
I deeply care about the architecture design, code quality, and agile methodologies.
In the past, I worked for Google, CERN, Hazelcast, and AGH University.

On a more personal note, I love running and mountaineering.
