Hanif Carroll

Hey, I’m Hanif. I’m an AI product engineer with eight years of experience building web, mobile, and AI products. I care obsessively about the details that turn working software into a quality product that people love to use.

I got into programming after deciding physical therapy wasn’t the path for me. While figuring out what I wanted to do next, I started watching Mr. Robot. The show hooked me and inspired me to learn how to code.

I went on to work at 8base, Capgemini, and LeagueApps, building products in environments that ranged from large consulting teams to fast-moving technology companies. Along the way, I learned how to turn ambiguous ideas into thoughtful, useful products without losing sight of the people using them.

Today I run HC Studio, a solo product studio building AI-powered products for early-stage founders. I recently shipped an AI-powered Amazon seller platform to its first 200 paying customers and built a Spanish reading app from concept to production across iOS, Android, and the web, with subscriptions and LLM features. I also enjoy thinking about UX, UI, marketing, and client acquisition.

Outside of work, I like to lift weights, experiment with AI, and have merienda in cozy coffee shops. My ideal order is a ham-and-cheese croissant and a slice of red velvet cake with a café con leche.
