A little design-minded.
A lot detail-oriented.
I turn complex product ideas into clear, accessible web experiences. Four years building with React, TypeScript, and a healthy attention to the details.
Less friction. More intention.
Selected work below01Selected work
A few projects, from a Web3 marketplace to backend systems, built with care across the whole stack.
A blockchain marketplace for buying businesses. Led the frontend from an inherited codebase to an investor-ready MVP, with wallet, Google and guest auth, on-chain transactions and a deal pipeline.
A fintech app for paying bills, trading gift cards, using virtual cards and managing crypto. Maintained and improved the core frontend and admin dashboard, led the new company website and built screens for the mobile app.
A Web3 community platform for cohorts and events. Built end to end, then split into separate frontend and backend services, with Paystack payments, email queues and NFT minting.
A multi-tenant team workspace backend with role-based access control, token-based invitations and queued emails, in a layered architecture with Zod validation.
Small teams. Real problems. Careful execution.
More experiments on GitHub02How I build
The part you see matters. So does the structure, speed, and care underneath it. I like working on both.
Reusable components, clear TypeScript contracts, and just enough abstraction. Code that the next person can comfortably work with.
Components / Systems / Type safety
Semantic HTML, sensible focus states, and keyboard-first interactions. Accessibility belongs in the first commit, not the last ticket.
WCAG / Responsive UI / Interaction
Measure first, then improve. Thoughtful loading states, lean bundles, and caching around the data that people actually depend on.
Web vitals / Caching / Resilience

A little about me
04A bit about me
I’m Henry Nmesomachukwu Okeke, a frontend engineer. I enjoy the space where design meets engineering, turning a good idea into something that feels natural to use and straightforward to maintain. I’m always poking at some new tech, and I never say no to a good conversation about it.
Outside of work, you’ll find me on a long walk, rewatching Brooklyn Nine-Nine or Modern Family, or watching Barça suffer and celebrate. I also play CODM, not so badly, and watch other people play it better. I’m happiest on teams that share what they know and care about the small things.
