HepNow, Kenko and Gamma were separate products sharing a stack: Next.js, GraphQL with Codegen, React Query and Firebase.
Because the products shared patterns, I built reusable hooks — cart, translation and other cross-cutting concerns — that became shared building blocks rather than being rewritten per project.
Highlights
- Three products on a shared Next.js + GraphQL stack
- Codegen-driven typed GraphQL clients
- Reusable cross-product hooks (cart, i18n)
