Who I am

A scientist, a mathematician, a programmer and an artist. Together, these four traits make me a problem solver and a creator — I get a thrill from crafting algorithms, and I love solving difficult problems. I graduated with degrees in physics and mathematics; two subjects that I am passionate about, and that introduced me to the power of data and statistical analysis.

What I do

I create custom algorithms to solve unique problems, and I use statistical analysis and machine learning to either mine data for useful insights, or create models that predict outcomes and/or reveal relationships between attributes of a subject. The possible applications are nearly limitless, and specifics vary with each project.

The bottom line: I optimize the performance of businesses and systems, make predictions & generate insights, and enable new methods with custom algorithms — all using scientific and mathematical methods.


Statistical Analysis & Machine Learning

The nutshell — I am capable of working on a wide variety of problems, with data sets that are either raw or clean, big or small. I recommend looking at some of my projects for specific examples.

A few business-relevant topics that fall within my abilities:

  • Marketing and sentiment analysis
  • Time series analysis and forecasting
  • Fraud detection
  • Risk minimization
  • User preference learning
  • User classification
  • Predictive analytics
  • Optimization problems

The jargon — Some terms relevant to my abilities are: regression, classification, optimization, cluster analysis, time series, ANOVA, data exploration, pre-processing, feature engineering, working with data imbalance, categorical with many levels, sparse matrices.

I am familiar with many machine learning algorithms, but my favorites are Artificial Neural Networks, Random Forest Classifiers and Naive Bayes.


I can develop just about anything using Python and its libraries — including (but not limited to) Theano, Scikit-Learn, NumPy, Pandas, Requests and Matplotlib. I am fully capable of setting up and querying SQL databases, and I have a great deal of experience with web-oriented languages.

A few of my coding projects can be found below, along with some of my data projects.
