Cross-platform sports and specialized sports English learning ecosystem (Web, iOS, Android), evolved from web prototype to native React Native mobile apps with Stripe and RevenueCat in-app subscriptions.
iOS & Android Mobile Applications
Mobile devices account for over 60% of all global internet traffic. I engineer native-feel cross-platform applications using Flutter (Dart) and React Native, guaranteeing 60–120 FPS fluid touch interactions, a unified codebase for both iOS and Android, and full support through App Store and Google Play approval.
Who is this service for?
- Startups pursuing a mobile-first product to test market product-market fit rapidly.
- Businesses creating a companion smartphone app for existing web services.
- Product creators demanding simultaneous iOS and Android reach within budget.
- Businesses with field teams (delivery, technicians, job sites) looking to replace informal WhatsApp chats and paper forms with a dedicated, synchronized mobile app.
#Problems solved
- ✕Prohibitive financial and maintenance costs of dual Swift and Kotlin codebases.
- ✕Clunky hybrid apps that lag during scroll or gesture transitions.
- ✕Complex App Store and Google Play review policies and submission hurdles.
- ✕Reliably managing offline data states, local caching, and push notifications.
