    Do you have some question that requires a statistical or machine learning answer? No problem. As a data scientist with 15 years of experience, I have the technical knowledge and the communication skills needed to solve your problem and, most important, give an answer that you can apply to your field of interest. What I offer to you is a full data analysis/machine learning stack, including: - Getting and organizing your data. - Selecting the most relevant statistical or machine learning technique for your case. - Applying the technique to your data. - Writing a report that explains every step taken and makes a interpretation of the results. All written with enough technical detail, but that doesn't require a depth statistical knowledge to follow. - Assistance in applying the results to your specific field. I can do all this using any or several of the following: R, MATLAB, Python, MySQL. Everybody can apply an out of the shell statistical algorithm to some benchmark data. But I'm an expert in the tricks needed to apply those algorithms to real data.

I also built customer segmentations for Canadian Tire Bank, which gave the executive team a holistic understanding of their customers for the first time and resulted in a chapter of a book. 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.
