About

I am a software engineer at ScyllaDB, building a fast, distributed NoSQL database. I am also a PhD student at the University of Helsinki, under PhD supervision from Sasu Tarkoma and mentorship from Ashwin Rao. I received my BSc and a MSc in Computer Science from the University of Helsinki in 2013 and 2016, respectively.

My research interests include operating systems, virtualization, and edge and cloud computing.
