BUILDING
SYSTEMS
THAT SCALE

Startups don't fail from bad ideas — they fail from slow APIs, broken backend logic, and products that can't scale past MVP. I fix that. I'm a full-stack developer specialising in backend systems and Web3 integrations, with 4+ years building production-grade platforms across fintech, SaaS, and blockchain.

Whether it's architecting a microservices backend, integrating payment gateways, or shipping a smart contract — I move fast, write clean code, and deliver work you can actually ship. My edge: I understand the full stack, so I don't create silos between frontend and backend decisions.

WHAT CLIENTS
ARE SAYING

Words from the founders, leads, and teams I've shipped with.

Ifeanyi joined us mid-sprint and hit the ground running — no hand-holding needed. He rebuilt our payment integration with Stripe and Paystack in under two weeks, fixing edge cases that had been causing silent failures for months. If you need someone who understands fintech complexity and still ships fast, he's your guy.
