Why We Built ZIMPUDO: A Maker Approach to Zimbabwe's Last-Mile Problem

Anyone who's tried to send or receive a parcel in Zimbabwe outside Harare or Bulawayo knows the drill: unreliable addresses, courier coverage that thins out fast outside the major cities, and the looming cost of door-to-door drop. We hit the same wall ourselves, shipping components to customers in Mutare, Masvingo, Bindura, Gweru. There had to be a better way. **Enter ZIMPUDO.** ZIMPUDO is BlitzTech Electronics' parcel-delivery platform, a network of smart lockers and self-service kiosks designed for the realities of Zimbabwean logistics. Senders book a drop in our app or on the web. Couriers deposit parcels into the locker network. Receivers pick up with a one-time code on their phone. Asynchronous, secure, and operable by non-technical kiosk staff. **The stack we built it on:** - **Backend:** Java with Spring Boot 3, a battle-tested, JVM-native platform with strong tooling for a small team to maintain - **Mobile:** Flutter, single codebase, native iOS + Android, fast iteration - **Web frontend:** Flutter web for parity with mobile - **Locker hardware:** STM32-based controllers we designed in-house, with secure compartment control and tamper detection - **Kiosk software:** Kotlin running on commodity Android 7 hardware Every layer is something a small Zimbabwean engineering team can maintain, debug, and extend, no vendor lock-in, no proprietary ecosystems, no surprise licensing fees. **Why this matters:** When a Zimbabwean small business in Mutare can offer their Harare customers same-day collection from a locker at the local kiosk, the unit economics of selling beyond your own city actually start to work. ZIMPUDO is our maker-built bet on that future. **Visit ZIMPUDO at [zimpudo.com](https://zimpudo.com).**
