My background is in the design and implementation of distributed, mobile, and
I work at ThoughtSpot.
Previously, at Samsung, I built SummaryStore, an approximate storage system
for cost-effective real-time analytics on ''colossal'' data streams, a
highly-available data replication service, and a fault-tolerant distributed
middleware for reliable smart-home applications. Prior to this, I spent 6 years
at NEC Labs where I led the Simba project to develop cloud infrastructure for
mobile data management.
I graduated with a PhD
from Wisconsin with Professors Andrea
Arpaci-Dusseau focusing on operating systems,
distributed systems, and storage systems.
