About

I am a Computer Science Graduate student at the University of Wisconsin-Madison. I interned at Meta during summer'22 in the WhatsApp Calling Infra team. I worked on unifying the routing infrastructure for WhatsApp and Remote Presence apps by building a router unit which forwards call media packets (~420K per minute per PoP on average). Additionally, I built a prototype to secure server inter-node communication using QUIC Protocol. Before joining UW-Mad, I was a Lead Engineer in the Samsung Internet Web Engine and Privacy team at Samsung Research Institute, Bangalore.
