Mushfiqur Rahaman Mubin
@mushfiqr
Mobile application developer specializing in Flutter with native Android/iOS integrations.
What I'm looking for
I’m a mobile application developer with 5+ years of experience across freelancing and full-time roles, with 15+ apps published on Google Play and the Apple App Store. I started with native Android development in Java to build strong grounding in Android internals and architecture patterns, and I now work primarily in Flutter for cross-platform delivery.
I deliver real production outcomes—one of my published apps holds 8,000+ Play Store reviews at a 4.9 rating. I use platform channels to write native Kotlin and Swift only when a feature genuinely needs native behaviour, so the product stays performant and reliable.
In my current role, I build cross-platform Flutter apps and integrate native VPN, ISP management, live sports streaming, and ride-sharing features. I also enjoy full-stack responsibility, handling Node.js + TypeScript backends end-to-end, and I’m careful to keep architecture clean so the codebase remains scalable and maintainable—no messy inheritance. I treat every engineering problem like a puzzle: methodically, curiously, and always after the cleanest solution.
