About
I’m Isaac Flath. I’ve spent 10 years building AI products across product management, data science, and engineering.
I write and teach about the data path from messy sources to a model’s context. I cover documents, images, tables, and application data: how to make them usable, find the right parts, and put those parts where the model needs them.
I’ve always enjoyed teaching. Before tech, I taught swimming, tennis, and ballroom dance. I continue to teach through my writing, videos, courses, and community.

I met my wife, Alyssa, when we were both teaching dance full time. She now runs Art of Movement, a dance instruction business in the D.C. area. We still dance together. This is our wedding dance routine (country mashup).
