AI Product Executive

Building ML and AI products since 2013.

From Spotify's personalization engines to True Fit's AI fit platform to Evertune's LLM brand analytics, I lead product organizations that ship AI products people actually use. I am an executive who still builds: strategy at the board level, prototypes in Python with Claude Code.
