• Developed a quarterly forecast model to predict sales of Tableau using a probabilistic time-series model GluonTS hosted on AWS Sagemaker, which improved error by 10% as compared to existing models• Created a model factory (generating 50+ unique models) using DataRobot to provide guidance on territory evaluation during the annual sales planning process, speeding up time to decision by 2x• Prototyped a discounting model to provide recommendations for optimal discount on a given deal based on account history and deal size. Additionally, the model predicts likelihood of a deal to be won and key features that impact deal success.

Automatic Redaction Pipeline:• Consulted with Empower Work, a peer to peer counseling service, to implement a previously non-existent data pipeline on AWS, which stores 100k conversations into a functional postgresSQL database, which allowed the company to instantly query data to that provided quantitative support for operational changes.• Developed a dashboard to allow for monitoring of key performance indicators, including conversation success rate, and tracking of trending topics.• Quantified the likelihood of a conversation needing redaction using Gensim Word2Vec and logistic regression. Reduced hours spent by analysts manually redacting conversations by 99%. Redacted personally-identifying information by training a spaCy model to perform named entity recognition.

• Detected and quantified anomalies in time series of surface displacements measured via GPS using a variety of techniques including Principal Component Analysis and Kalman filtering in MATLAB and Python. • Modeled tectonic plate motion using GPS surface displacements and a combination of linear regression and Tikhonov regularization.• Quantified biases introduced by hyperparameters in the filtering method by performing sensitivity tests. • Implemented a density-clustering algorithm DBSCAN to automatically create a catalog of tiny earthquake locations.• Increased the signal to noise ratio of small GPS signals by stacking time series and performed common mode filtering to remove large regional biases in spatial data.
