Utilized Natural Language Processing (NLP) to develop convolutional neural network models for predicting job titles based on resume job description. Neural network models produced word and character level embeddings respectively to aid in autocompletion of sample job summaries given a job title. Model deployed using python and flask.

Developed Long Short Term Memory Network (LSTM) prediction model for forecasting numerical demand of live events utilizing social Twitter data and internal data. Engineered features were later allocated to models for ticket sales predictions.

Developed and evaluated a fine-tuned Extreme Gradient Boosting (XGB) model to predict if a user will go from landing page to the initial checkout page. Model later used to increase customer engagement by 2% on user platform.

Developed and evaluated time series and logistic regression models to better understand what factors lead to customer satisfaction with the goal of increasing conversion rates from trial to activation of a subscription service by 3%.

Developed an Android Unit Test Automation Framework for Mobile Application and effectively decreased the amount of time devoted to Unit Testing.

Developed health-related food recommendation models that consider consumer's eating and lifestyle habits as well as ingredients of recipes the user enjoys to make healthier recommendations. Executed NLP techniques such as word and character level embeddings as input to the models.
