About Me

Currently, I am working as a Software Engineer at Salesforce.com in the Search Infrastructure team. I work with Apache Solr, Docker and Jenkins. I pursed my MS in Information Networking at Carnegie Mellon University. My focus of study was Distributed Systems. I am interested in understanding how current large-scale distributed systems are built and how to achieve scalability, caching and fault-tolerance in distributed systems.

In my previous incarnation, I was a hardware tinkerer.
