Shop Tumira Thumela

People working in South Africa want to buy groceries and building materials for relatives in Zimbabwe and have them delivered directly, paying with local methods.

A storefront and a separate admin CMS, kept in one monorepo so they share types, validation and UI components but deploy independently. The first version (2019–2021) was a MERN-stack web and mobile platform with local payment gateway integrations; the current version is rebuilt on Next.js and PostgreSQL.

• A Turborepo monorepo shares schemas and components between storefront and CMS.
• Checkout supports South African payment methods, with fulfilment handled from Zimbabwe-side warehouses.
• Role-based access in the CMS so warehouse staff only see what they need.

• Live storefront at shop.tumirathumela.com.
• A native app I delivered earlier for the business reduced operational inefficiencies by about 30%.
• Mentored junior developers on the original team.
