Bio

Pekka Enberg is the Founder and CTO of Turso and a PhD Candidate in Computer Science at the University of Helsinki. He received his M.S. in Computer Science from the University of Helsinki in 2016. In the past, Pekka has worked on the Apache Cassandra-compatible low-latency, high-throughput distributed database system, ScyllaDB, as well as on the Linux kernel as a contributor and maintainer of SLAB memory allocators and the OSv unikernel, an operating system designed to run efficiently on the cloud. His current research focuses on the intersection of low-latency networked systems and serverless edge computing.
