01About

I'm a full-stack developer based in Nigeria, specializing in React, Next.js, TypeScript, and Express.js. Recent work centers on two things: integrating LLM-powered features into real products — symptom-assessment agents, medication adherence agents, autonomous content agents — and working with payment infrastructure, from virtual account architecture to webhook-based reconciliation. Certified in Nomba Payment Systems (Jul 2026).
