The Engineer
Behind the Stack.

4 years shipping production-grade AI, DeFi protocols, and enterprise systems — built to last, not just to launch.

I'm a software engineer with deep expertise in artificial intelligence, blockchain infrastructure, quantitative finance, and full-stack web development.

I architect production-grade systems that bridge traditional finance with decentralized protocols — including crypto offramp & onramp infrastructure — and build AI-powered tools that solve real-world problems in fintech, DeFi, IoT, and enterprise software.

My quantitative research covers Black-Scholes options pricing, ARIMA forecasting, GARCH volatility modeling, and Portfolio VaR analysis, applied in live trading systems and research contexts.

My web engineering work spans production backend systems built in Python, TypeScript, and PHP. I have delivered enterprise e-commerce infrastructure and tax-tech SaaS products designed specifically for the Nigerian market — with deep integrations into Paystack, Monnify, and other Nigerian payment gateways.
