Galvanize Feb 2016-Current

Data Scientist in Residence San Francisco, CA

Giving lectures, teaching and mentoring Master students of Galvanize University for a two-month course in data engineering which covers Advanced SQL, Linux, AWS, Docker, Advanced Spark, NoSQL, MapReduce

Completed Galvanize data science immersive program with project-based curriculum that focused on data processing, machine learning and data visualization

Patent search tool:

Worked with 300 GB of XML patent data obtained from USPTO and created a MongoDB database. Using Spark, Python and NLP on AWS (EC2) created a patent search tool which can be used to invalidate new claims

Loan predictor: Applied NLP analysis to classify models and find the most important factors that affect loan interest by Random Forest, Ada Boost and regression models.

Scraped/processed NYT articles and used K-Means clustering to discover underlying themes/topics.

Built movie recommender using matrix factorization on ratings dataset to predict new movie ratings.

Classified credit card fraud using a Random Forest Classifier that focused on optimizing recall.

Used MongoDB to accept JSON pings and output new Fraud predictions on a web-app interface.

Predicted user churn at a ride-sharing company using a Gradient Boosted classifier. Western Digital (WD) Oct 2013- June 2015

Staff Engineer Irvine, CA

Failure/error analysis using sum-product networks (deep learning) - Fault-Tolerance techniques: Designed advanced algorithms to improve fault-tolerance of big data analytics jobs (Patent disclosure submitted). Analyzed failures in data written in flash memories. The algorithms (sum-product and message passing algorithms) were developed using C++ and Python for several projects.
