02. About Me
Who I Am
I'm a Full Stack & Blockchain Engineer based in Lagos, Nigeria. I specialize in building production-grade Web3 payment infrastructure, EVM-based decentralized applications, and scalable backend systems.
At Wellnite Inc. (US), I architect and ship full-stack features across a complex telehealth platform. Outside of work, I build open-source projects like ChainPay — a non-custodial Web3 payment gateway — and an AI-powered job search assistant.
My toolkit spans TypeScript, Next.js, Node.js, Solidity, Foundry, PostgreSQL, Docker, and cloud deployments on AWS & VPS infrastructure.
