Marjon Customer Cabinet

Marjon Customer Cabinet is a customer-facing web portal for business clients of Marjon in Uzbekistan. It is built as a pnpm + Turborepo monorepo that hosts two products: Marjon Reklama, where customers create and track advertising deals on vehicles, review payments and follow vehicle routes on a map, and Marjon Yuk, where they manage cargo, packages and shipment tracking. The app follows Feature-Sliced Design with strict one-way dependencies between the host app, the domain packages and a shared design system, and is localized in Uzbek and Russian.
