01 / Geo infrastructure

60,000 farms, walked and mapped

A GPS boundary-capture flow for field agents across northern Nigeria, built for cheap handsets in places with no usable signal.

02 / Logistics at stake

$5M in seed. Zero loss.

The distribution app that moved five million dollars of agricultural inputs to more than a hundred thousand farmers, with every handoff verified.

03 / Platform foundation

One platform, every app

The offline-first sync layer every app in the company runs on, and the spine of a multi-tenant platform rebuilt from a single-module monolith into forty-nine modules of pure Compose.

How the team got there

  • Guidelines before features

    Wrote the mobile development guidelines the team still runs on: project structure, review bar, release checklist, every commit tied to a ticket. ISO 27001 compliance runs as audit tooling inside CI. Crash-free sessions hold at 99.8%.

Grown from twelve, across four seniority levels. Four hires onboarded and all still here two years on, writing production Compose inside two months.

Five years of Android work, most of it at Babban Gona, counted honestly.
