We build delightful
app solutions.
Big Belly Studio is a small, focused software studio designing and shipping thoughtful mobile and web products — from first sketch to the App Store.
What we do
Full-stack product building, start to finish.
One team, end to end. We handle the design, the code, and the cloud so ideas ship as real, polished products.
Product & UX design
We shape the whole experience — flows, interface, and the little details that make an app feel effortless.
Mobile & web development
Native-quality iOS apps and fast web products, engineered to ship and built to last.
Cloud & AI integration
Scalable backends and thoughtful AI features, deployed on modern cloud infrastructure.
Featured product
Wedding planning,
finally fun.
A warm, guided journey that turns the whole wedding to-do mountain into one cozy roadmap — checklist, guest list, budget, gallery and an in-app AI assistant, all on your phone.
The founder
A studio of one — with the range of a whole team.
Big Belly Studio LLC is founded and run by Yu-Sheng Tu, a solo owner and developer based in Orlando, Florida. Every product is designed, built, and shipped end to end — with the care of someone who owns the whole thing.
Small by design. That means fast decisions, real craftsmanship, and products that actually feel good to use.
Built with modern infrastructure
A lean stack, powered by best-in-class cloud & AI.
Let's build something
worth shipping.
