Deloitte Consulting | Nov 2017 - Mar 2019

Senior Consultant

● Used a variety of Gaussian and Gaussian Mixture models to address business needs of a large federal client. Delivered solutions to difficult problems of imputation, anomaly detection and estimation. ● Worked extensively with Postgres and SQL programming to produce complex permanent tables and stored procedures in support of developing new models of identity theft. ● Contributed to the development of an internal course on optimization focused on a variety of potential client business cases and delivered via Juypter Notebooks. ● Contributed to the development of project workflow management, leveraging GitLab for project documentation, code repository, and version control.

The George Washington University | Aug 2015 - Nov 2017

Professorial lecturer

● Contributed to improved curriculum development through collaboration and discussion with lead professor at GWU school of engineering and applied science. ● Provided lectures on multivariate data analytical methods including: regression, principal components for dimension reduction, and analysis of variance. ● Deployed Jupyter Notebook web application to aid the communication of abstract probability theory whilst teaching data analysis course.

Personal | Jan 2015 - Present

Statistical Machine Learning

● Latent Dirichlet allocation (LDA) for document retrieval task. ● Approximate nearest neighbor using KD-trees and locality sensitive hashing (LSH). ● Probabilistic mixture models for document clustering. ● Linear regression models for predictive analytics and feature selection. ● Nearest neighbor and kernel regression for predictive and classification tasks. ● K-means for document clustering tasks. ● Logistic regression for classification tasks. ● Decision trees for multi-class classification tasks. ● Use of ensemble classifiers for boosting model performance. ● Validation set and cross validation for parameter tuning. ● Bias-variance trade off using L1 and L2 penalties. ● Gradient and Coordinate descent for parameter estimation. ● Stochastic gradient descent for batch and online parameter estimation.

Clearview Consulting | Feb 2013 - May 2015

Consultant

● Met with client’s senior leadership during project initiation to scope project requirements and establish business goals and objectives. ● Conducted interviews with staff, in conjunction with, document analysis to better understand existing data collecting infrastructure. ● Consolidated disjoint data sets from csv text files, excel files and mySQL databases by importing and merging using pandas. ● Used pandas and Matplotlib to conduct data quality assessment and exploratory data analysis in aid of assessing and communicating deficiencies in client’s data collection procedures. ● Utilized regression and classification techniques to provide insight into a variety of supervised learning business use cases; including logistic regression for sentiment analysis and; prediction of default rates using gradient boosted decision trees. ● Performed statistical analysis of data using Python programming, developed reports using Tableau, and utilized Python to build analytic tools for quantitative modeling. ● Leveraged python beautifulsoup4 module to collect and organize structured and unstructured web data used in developing predictive models. ● Used locality sensitive hashing for unsupervised approximate nearest neighbor document retrieval. ● Explored high dimensional text datasets using a variety of machine learning classification techniques, including k-means and diagonal gaussian mixture models. ● Leveraged topic modeling for the calculation of mixed membership in document corpora. Used latent dirichlet allocation (LDA) to learn and identify topics present within corpus.
