What I'm looking for

Fully remote role as a Senior or Mid Flutter / mobile developer, or a mid-level React / Next.js front-end or full-stack developer. I want to own features end to end, from Figma to App Store, Google Play and production web. Based in Nigeria (UTC+1), available immediately, happy to overlap EU and US hours.

I am a senior Flutter engineer and a product-minded front-end and full-stack developer. I build mobile apps, production web platforms, and the Supabase and Node.js back-ends behind them, and I want a hands-on role where I own features from first commit to release.

Mobile: Flutter and Dart with Riverpod or Bloc, GoRouter, fpdart and Clean Architecture, with TestFlight, App Store and Google Play releases handled myself. Communitee Golf, a golf community app with Stream Chat and push notifications, is live on the App Store. For Beepex, a fintech app, I built Paystack wallet funding, airtime, data, electricity and TV bill payments, and PIN-protected transactions on Supabase edge functions. For VotixCare I built the Flutter patient app. At QHarbor Research I upgraded the HDF5 Dart bindings to zero-copy dart:ffi, making 10M-element loads about 5x faster (40 ms vs 200 ms) with 50% less memory.

Web: React, Next.js (App Router), TypeScript, Tailwind CSS, shadcn/ui, Framer Motion and Vue.js. Live work I built:

VotixCare, a practice-management platform for optometry clinics: marketing site and the clinic app with appointments, payments, reconciliation and reporting (votixcare.com, app.votixcare.com)
- Evvy Hairs, an e-commerce store with admin, installment payments and an affiliate system (evvyhairs.com)
- Forza Projects, company site and operations dashboard (forzaprojects.com, app.forzaprojects.com)
- Chiefs House, a membership site on Next.js, Supabase and Cloudflare (chiefshouse.com)
- RIVCHPP, the Rivers State Contributory Health Protection Programme portal (rivchpp.icowebagency.com)
- Julirose Hotels (julirosehotelsandsuites.com), Gerald Nwoye Foundation (geraldnwoyefoundation.org), HD Attitude Studios (hdattitudestudios.com) and ICOWEB Agency (icowebagency.com)

Full-stack: Node.js, NestJS, Express, Supabase and PostgreSQL, including SQL migrations, row-level security, edge functions, payment webhooks and transactional email.

Based in Port Harcourt, Nigeria (WAT, UTC+1). Fully remote, available immediately, comfortable with any time-zone overlap. Portfolio: smithportfolio.smitho.workers.dev
