More recently, I have built a linear regression model to explain the relationship between interest rate of peer-to-peer loans and borrowers' characteristics using data from LendingClub, a two-level clustering-and-randomForest model to predict human physical activities using smartphone data, a logistic regression optimization based on precision and recall, a R-implementation of the cross-sectional regression and quintile-portfolio construction methods published in the Journal of Economic Literature. I have a masters degree in Biostatistics from the University of Michigan and a bachelor's degree in mathematics from New College of Florida. I'm an avid MOOC taker, constantly learning new techniques and tools in data science and machine learning.

    My unique approach to financial management is designed to reveal both insights and opportunities. Building upon a background of National Account Management, Commercial Banking, Brokerage Services, and Senior-Level Financial Consulting, I draw upon a wealth of practical, first-hand experience to benefit clients in the ways that matter most: A broad-based understanding of business finance that achieves defined, sustainable goals. A common theme linking disparate industries at different stages of development and maturity comes courtesy of an understanding of the flow of every dollar, from sales to expense to operating income. Examined through a lens that is customized for every client and each business, and reflects their unique challenges and competitive advantages.
