Hey, I’m Hanif. I’m an AI product engineer with eight years of experience building web, mobile, and AI products. After working at 8base, Capgemini, and LeagueApps, I now run HC Studio, where I turn ambiguous ideas into useful, production-ready software. Recent work includes helping Genrupt reach its first 200 paying customers and taking Palabruno from concept to production across iOS, Android, and web.

I got into programming after Mr. Robot inspired me to learn how to code. Outside work, I lift weights, experiment with AI, and have merienda in cozy coffee shops.
