What I'm looking for

I'm looking to build reliable, zero-to-one AI-powered and event-driven products, especially for commerce, payments, and financial services in African markets. I value end-to-end ownership from architecture and infrastructure through deployment.

I've built zero-to-one platforms including wapisales, a multi-tenant WhatsApp commerce system with AI-powered customer interactions and Paystack payments, and Diko, an offline-first platform for informal group savings. I architect full-stack products in TypeScript and Python, from infrastructure and CI/CD through production.

My work spans event-sourced payment systems, microservices, LLM-powered invoicing, mobile applications, and automated trading signals. I focus on reliable systems that solve practical challenges such as offline access, payment verification, data integrity, and trust in African markets.
