05 / About

I'm a product engineer who thinks like an owner. I've shipped interfaces to real users in informal, low-connectivity markets, which taught me the most honest design is the one that actually loads, actually converts, and actually earns trust.

On MealFed, a live food-delivery iOS app for underserved Nigerian cities, I built the full Flutter UI — customer ordering, vendor dashboards, real-time tracking — with offline-first behaviour and landmark-based input for low-bandwidth environments. I replaced star ratings with repeat-order signals as the primary trust cue, and designed a WhatsApp-first vendor onboarding flow to remove app friction for small merchants.

Beyond that I've built 15+ production websites, web apps and SaaS frontends for clients across the UK, Nigeria, Indonesia, South Africa and pan-African markets — specialising in multi-surface systems where a public site, a portal and a mobile app all share one design language.

Based in Lagos and collaborating worldwide. Available for focused builds, end-to-end product partnerships, and embedded product engineering.
