My name is Sagar Patwardhan and I am a software engineer at Yelp Inc. I am part of the distributed systems(Infrastructure) team. I have been with Yelp for a little over two years; I am currently working on building mesos infrastructure and next-gen batch processing infrastructure at Yelp. My previous projects include an asynchronous processing system called kew, which is used for processing all of Yelp's emails, push notifications and online transactions in real time. I also worked on our distributed, fault tolerant, concurrent task executor called seagull, which is used for running millions of tests every day in a cost effective manner. I got my M.S. in computer science(specialized in distributed systems and networks) from USC. I was part of the networked system lab where I did research in TCP. I got my B.E. in computers from University of Pune, India.
