The build
The proof that this studio ships real products, not just sites. A full multi-tenant SaaS: an admin portal for institutes plus an Expo parent app on iOS and Android. Institute-level data isolation enforced by 52 RLS policies over 18 database functions, AI-generated progress reports, signed-URL study materials and push notifications — built solo in roughly six months, live on the App Store.
The standout
Multi-tenant isolation done properly: 52 row-level-security policies, staging/production separation, Sentry monitoring and a full CI/CD pipeline — one founder, end to end.
The outcome
Live on the App Store — a multi-tenant SaaS with a parent app on iOS & Android, built solo in roughly six months.
