What I'm looking for

I'm looking to build secure, production-grade web products, especially fintech and payment systems, where I can own work end to end and contribute to remote teams serving international users.

I built SplitPayNG, a Nigerian subscription-sharing fintech platform with real Paystack payment flows, automated billing, and 48-hour escrow workflows.

I secure production applications with AES-256-GCM encryption, webhook verification, atomic database transactions, environment-managed secrets, and PostgreSQL Row-Level Security. I also completed a security self-audit that resolved 10+ critical, high, and medium-severity bugs.

As a freelance full-stack developer, I've delivered web applications for international fintech, media, and SaaS clients, including GuestVue, an event photo and video-sharing platform with an FFmpeg transcoding pipeline. I take projects from technical scoping through deployment and client communication.
