Overview

During lockdowns, I kept wondering - why were some bike stations still busy while others emptied? The data had answers, but needed translation.

I led the visualization layer of a machine learning system that decodes pandemic impacts on urban mobility. Using SHAP values, my heatmaps and interactive modules let users click any station to see exactly why ridership changed. Now urban planners can stop guessing and start data-talking with citizens.
