0→1 Data Science. From applications to analysis.

I lead data science teams at Starbucks and build personal projects here to explore what's next in data science, AI & software. Everything is open source—explore the analysis or follow along.

Each app applies a data science method to a real problem. Interact, contribute data, and explore the published analysis.
