01 / Overview

The Scope & Objective

Kokeb needed a unified marketplace platform capable of handling thousands of concurrent transactions, supporting multiple local payment gateways, and enabling vendor self-onboarding — all in a market with variable connectivity conditions.

02 / The Challenge

Operational Friction & Bottlenecks

Ethiopia's payment infrastructure is fragmented across Telebirr, CBE Birr, and Amole. Building a reliable checkout flow that gracefully handled partial payment failures and gateway timeouts was essential to prevent cart abandonment and revenue loss.

03 / The Solution

Architectural Implementation

We built a saga-based distributed transaction orchestrator that managed multi-gateway payment flows with automatic fallback routing. The mobile app used offline-first architecture with background sync, ensuring usability on 2G/3G networks.
