I am an Engineering Manager at Monte Carlo Data. I lead a team of software engineers to build the core data monitoring product.
I was an Engineering Manager at Reddit till Feb 2022, leading a team of software engineers to build revenue critical streaming and batch processing pipelines foundational to ad-serving, reporting and billing. I joined Reddit in 2017, where I lead work in Ads-Targeting: building features to match advertisers with their right audiences and in Data Engineering: building data ingestion & warehousing flow, growing pipeline 30X to 20 billion raw events/day.
I was a Research Engineer at Lithium Technologies and Klout between 2012 and 2017, building large scale data processing pipelines and machine learning models to measure user influence in social media.
I graduated from the University of California, Davis with a PhD in Computer Science in 2012. I was advised by Prof. S. (Shyhtsun) Felix Wu. My research area was software systems built on social networks to power search engines.
I dabbled in economic data analysis and worked with World International Patent Organization (WIPO) through Prof. Travis Lybbert, UC Davis to develop software systems based on text processing and keyword extraction models to analyze trademark and economic data.
Details of my professional experiences are on LinkedIn.
