Hey 👋, I’m Abu Saleh, a professional Mobile App Developer building modern Android and iOS apps for businesses, startups, and entrepreneurs worldwide.
I develop in Flutter, so both platforms come from a single codebase- fast, scalable, and user-friendly, at one build cost instead of two.
With 3+ years of experience, I handle everything from UI design and development to API integration, testing, and Play Store and App Store submission. You get full source code at handover.

I had the Figma design ready and mainly needed someone to turn it into a Flutter app. Abu did a good job with the implementation and shared the APK so I could test it on my phone. I noticed a couple small things with the splash screen and back button, and he fixed those pretty quickly. Everything is looking good now
