Full-Stack Engineer · AI/ML Builder · Blockchain Developer · Product Strategist
I build end-to-end digital products — from pixel-perfect frontends to production infrastructure — and lead ventures that sit at the intersection of AI, fintech, and emerging markets.
I'm the founder of AmadiFi Limited, a technology company based in Lagos building software, AI systems, and digital infrastructure across multiple verticals. I operate across the full stack — writing production code, architecting systems, and shipping business strategy simultaneously.
My work lives at the edge of AI × fintech × African markets. I'm currently building:
- 🤖 AdCopyLab — an AI SaaS that predicts ad performance before spend, currently in pre-seed raise
- 💳 Crypto payment infrastructure for Next.js/Convex webapps, including KYC-free privacy-first processors
- 📦 Digital product publishing under intellimesh.xyz with Paystack integrations, affiliate tracking, and multi-tier pricing
I don't just write code — I ship complete systems. Landing pages, checkout flows, email pipelines, government-grade proposals, investor decks. If it can be built, I've probably done it end to end.
