About Chris Ryan

I am a data science professional & software developer with over 12 years of experience. I specialize in the Python ML / data science stack (pytorch, numpy, pandas, scikit-learn, statsmodels, jupyter, and many others), cloud (GCP), as well as analytics platforms & tools like Looker, dbt, and Redshift/Postgres SQL. Over the years I have contributed to numerous data products, as both a team leader and senior contributor, at growing small-to-medium stage startups. I bring a sense for hypothesis-driven and innovative problem solving to my work developed during my time as a computational scientist. I also believe in clean coding practice, structured product / project management, rapid prototyping, and effective cross-functional collaboration.
