About Me

I'm a software engineer with hands-on experience building and maintaining reliable backend systems in fast-paced product environments. I care deeply about writing clean, maintainable code and delivering practical, high-quality solutions.

At Iterative Financial, I worked on partner payment integrations, SDKs, backend migrations (Node.js/Express to NestJS, RabbitMQ to River), and real-time config systems—helping make our systems more reliable and productive. I enjoy building systems that balance good architecture, developer experience, and real-world reliability.

  • 🔭 Currently building cross-border payment infrastructure at Iterative Financial, Inc.
  • 🛠️ Co-led a successful migration of a production system from Node.js/Express to NestJS (TypeScript), improving maintainability and scalability.
  • 📦 Author of @odunlamizo/node-river — a TypeScript library for the River job queue.
  • 🌍 Based in Lagos, Nigeria, building fintech solutions for Nigeria and beyond.
