Donell M.

I build AI-powered mobile and web apps that ship to the App Stores, raise funding, and serve real users. As CTO of Worlds of Hello, I designed and developed 4 production apps (Flutter + Supabase + Stripe + AI) that secured $400K+ in pre-seed investment. One hire instead of two, I handle product design and engineering.
