PRODUCTS

Things I own, not things I was hired for.

Ventures built end to end — commerce, reputation intelligence, business automation, and location-based experiences. Each is a real business rather than a portfolio exercise, which is why the status on each one is stated plainly.

Client and employer engineering work lives on Projects.
