Are you building a mobile app and need someone who actually ships? I'm Duaine, an Android & Flutter developer who builds production-ready mobile apps that work in the real world: low connectivity, heavy media, complex workflows, and real users. Whether you're a startup validating an MVP or a business replacing a legacy app, I'll take your idea from design to Google Play / App Store — with clean architecture, smooth UI, and code that's easy to maintain as you grow. What I build: Native Android apps (Kotlin + Jetpack Compose) — modern, reactive, scalable Cross-platform apps (Flutter/Dart) — one codebase, iOS & Android Offline-first apps — Room, WorkManager, background sync, local caching Media-heavy apps — video/image upload, compression, optimized file handling Full-stack integration — REST APIs, Firebase, Supabase, OAuth2, push notifications Industries I've worked in: Productivity, health & fitness, media/entertainment, e-commerce, and logistics. Why work with me: I write clean, well-architected code (MVVM, DI, modular), communicate clearly at every stage, and treat your deadline like my own. My goal is a long-term working relationship — not a one-off contract. I don't just deliver code. I deliver a working product you're proud to ship. 📩 Send me a message — let's talk about what you're building.
