About

One person, end to end

One Jellie is a one-person studio. I handle the whole arc — product thinking, design, and engineering — shipping each app from the first idea to the App Store, with AI as a force multiplier, not a crutch. The throughline is care: small, warm apps that are genuinely useful.
