<p>
I am currently exploring new opportunities. I am very interested in building opinionated products that focus on impact for the end user.
</p>
<p>
From 2012 to 2022, I worked at Twitter creating new products and systems in the space of recommendations and machine learning.
Six months after I joined, me and a few team-mates started a new product called <a href="https://blog.twitter.com/en_us/a/2013/stay-in-the-know" target="_blank">MagicRecs</a> for real-time recommendations.
I was the lead engineer for MagicRecs and helped it become a key growth driver for Twitter.
In 2017, I created a new technology called <a href="KDD_SimClusters_paper.pdf" target="_blank">SimClusters</a>,
which enabled a quantum leap in Twitter’s ability to model user interests and spin up new recommendations products effortlessly.
At Twitter, I was fortunate to work with wonderful colleagues who trusted my ability to rise to new challenges.
I held the role of a Principal Software Engineer at the time I left.
</p>
<p>
Previously, I did my Ph.D. at Ohio State University. My favorite papers from my Ph.D. is the work on <a href="http://vldb.org/pvldb/vol5/p430_venusatuluri_vldb2012.pdf" target="_blank">BayesLSH</a> and the work on
<a href="https://scholar.google.com/citations?view_op=view_citation&hl=en&citation_for_view=0PggaO8AAAAJ:d1gkVwhDpl0C" target="_blank">Directed graph symmetrizations</a>, both of which
influenced the SimClusters work I did later at Twitter.
