WORK EXPERIENCE
Data Science Intern Editorialist YX September 2020- Present
• Developing a personalized home-page experience on the e-commerce website using item-based filtering. Designing
data pipeline, pre-processing more than 5 million products, extracting client preferences and activity on the site, and
provide top 50 relevant products. [unsupervised learning, recommender system, Information Retrieval, AWS]
• Building “relevant” sort order on search results to improve customer click rate on the first page of the search results
using hybrid content-collaborative filtering model. [PostgreSQL, machine learning, sklearn, nltk]
Research Assistant University at Buffalo October 2019 – September 2020
• Developed a data pipeline from collection to qualitative analysis of “Problem Typology” based on intramural projects
and interventions. Research funded by the National Science Foundation [Clustering, Python, R]
Software Engineer, Machine Learning Motorola Mobility LLC January 2016 – July 2019
• Built a “Context Awareness Engine” to track phone activity and usage patterns and identify activities like driving,
sleeping, running, at_home, at_work, etc. using on-device machine learning. This library-as a service was used by
7 other applications to serve their customers [Supervised learning, Clustering, TensorFlow, Java, Android]
• Developed a recommender system to predict the top 5 applications the user might use, and the settings on the mobile
phone using the phone usage pattern [Recommender system, Bayesian Statistics, Android, Kotlin]
• Built AT&T cross-platform messaging service with real-time syncing, cloud backup, and restore for Motorola phones.
Further optimized to run on low memory and low power devices. [ RestAPI, Java, SQLite, Android]
• Developed “MotoBody”, a fitness application for smartwatches to track steps, calorie-burn, heart-rate etc. analyse the
trends and provide insights on the mobile phone. This application was downloaded by over 1 million people on the
android play store with over 350,000 active users. [Wearables, Java, Android]
SELECT PROJECTS
Winner of MTA Back on track (Microsoft Hackathon): Performed feature engineering and statistical analysis on the
passenger data and built a model to predict the number of people traveling on a route on any given day using Azure services.
