About

Smith Abiodun Osagie, side profile

Fig. 02, B.Ed. Mathematics

From a mathematics classroomto apps in two stores andproducts live on the web.

Four years of commercial Flutter and Dart work across fintech, healthcare, ride-hailing and education. I own features from architecture through REST integration, tests and code review to TestFlight, App Store and Google Play release, with Riverpod and Clean Architecture as my primary tools.

Since late 2025 I have shipped 30+ Next.js, React and TypeScript products through ICOWEB Agency, on whichever backend fits the job, Laravel, Node.js or Supabase, the design and engineering studio I founded: e-commerce storefronts, admin and finance dashboards, booking and ticketing sites, and marketing sites.
