Pavel Emelyanov, Principal Software Engineer at ScyllaDB

Pavel "Xemul" Emelyanov is an ex-Linux kernel hacker whose past experience includes containerizing Linux and the foundation of the project called CRIU. Pavel joined the ScyllaDB core team at the end of 2019 (which probably explains some extra throughput brought to the NoSQL world since then).
