CV
Education
- B.Tech. in Computer Science, IIT Bombay
- M.S. in Computer Science, University of Massachusetts, Amherst
- Ph.D in Computer Science, Brown University, 2025 (expected)
Work experience
- Summer 2018: Data Science Intern
- Researched the causal effects of user connections in social networks using deep variational auto-encoders for a large data set with millions of connections
- Selected as top 5 master’s students at UMass Amherst, from all the applicants.
- August 2016 - July 2017: Senior Machine Learning Engineer at LinkedIn
- Led the video classification project. Trained Deep Learning models and deployed them to production to handle more than 1000 fps, using asynchronous processing on GPU clusters
- Researched the training of Hierarchical Neural Auto-Encoders by introducing Neural Machine Translation type architecture and Tensorflow. Achieved 2x speed up.
- Experimented with multiple implementations of a popularity based model, to achieve significant improvements in user engagement. Applied a Thompson sampling based explore-exploit model to engage cold users with companies
- July 2014 - July 2016: Machine Learning Engineer at LinkedIn
- Developed and maintained a high QPS service, which classified ALL the content created on LinkedIn (millions of entities every day) to filter out spam. Designed various parts of the system: training pipelines for machine learning models, deployment, synchronous and asynchronous classification
- Worked on a Hackday project to auto-classify advertisements posted on LinkedIn using SVM. The work lead to reduced wait time for ads to go live on LinkedIn.
- May 2013 - July 2013: Software Engineering Intern at Amazon
- Developed internal tool for seamless remote compilation and deployment
