Ed Chen

Data Scientist

Data scientist with a CS degree and background in finance, with a passion for counter-intuitive analysis. I use data to interrogate received wisdom — finding what the numbers reveal that conventional narratives miss.

Portfolio Projects

Video Store SQL Analysis

Coming soon — A rebuild of my Udacity data science SQL capstone as an interactive web application. The dataset is a fictional video rental database — Udacity's choice of subject, not mine — but the analytical methodology is original and remains relevant: a novel approach to identifying customer content preferences from behavioral data and cross-referencing against revenue contribution.
