I will build your android or flutter app from scratch to launch


About this gig
I'm a Senior Android Engineer with 9+ years of software engineering experience, currently working at Samsung R&D Institute Bangladesh, where I build the Galaxy Watch Manager app shipped across 6 consecutive Galaxy Watch flagship releases to 5M+ users.
I build native Android apps in Kotlin using MVVM architecture, Jetpack Compose/XML for UI, Hilt for dependency injection, Coroutines/Flow for async work, and Retrofit + Room for networking and local data. I'm also expanding into Flutter for cross-platform builds most recently on a voice-AI hackathon app using real-time voice (Agora Conversational AI) with a Node.js backend deployed on Docker/GCP.
What I can build for you:
Native Android apps (Kotlin/Java, Jetpack Compose/XML)
Flutter cross-platform apps (Android + iOS from one codebase)
API integration and offline-first data layers
Clean, testable architecture not just a working demo
How I work:
I scope the project with you before starting so we're aligned on features and timeline. You get full source code, and I explain the architecture so your app stays maintainable after delivery not a black box.
Let's talk about what you're building.
