FlowMart
01 / Executive Summary
FlowMart is a cloud-native, multi-tenant B2B marketplace and supply chain platform built to modernize wholesale distribution across West Africa. The platform connects manufacturers, distributors, and retailers in a single transactional layer — enabling real-time inventory visibility, automated procurement workflows, and embedded financial services.
As the Lead Cloud Architect and Backend Engineering Lead, I was responsible for the complete system architecture from initial design through to production deployment. The primary technical challenge was building a platform capable of handling 50,000+ concurrent sessions with consistent sub-150ms P99 API latency, while maintaining strict data isolation between tenant organizations in a shared infrastructure environment.
The architecture is built around an event-driven microservices pattern deployed on AWS EKS, with Apache Kafka as the central nervous system for asynchronous inter-service communication. The system processes over 3 million events per day with full audit trail compliance required by Nigeria's SEC fintech sandbox.
