Hi, I'm MD Naim Mia
I build cross-platform mobile apps with Flutter — from the first wireframe to the App Store listing. I care about apps that load fast, hold a steady 60fps, and stay easy to change as they grow.

About Me
Mobile apps that hold up in real users' hands.
I'm a Flutter developer and software engineer. I build mobile apps for startups and agencies, and I like the part of the job where a messy problem turns into something that's simple to use.
Cross-platform Mobile Apps
iOS and Android from a single codebase, without the app feeling generic.
Firebase Integration
Auth, Firestore, Storage, push, Crashlytics, and analytics.
REST API
Typed API clients with caching, retries, and offline handling.
Clean Architecture
Layered, testable code a team can work in without stepping on each other.
Performance Optimization
Smooth scrolling and fast startup, measured with the profiler instead of guessed.
UI/UX Implementation
Designs built to match, with the small interactions that make them feel finished.

What I do
What I help with, from the first sketch to a maintained app in the stores.
Flutter App Development
iOS and Android apps from one Flutter codebase, structured so they're still easy to change a year later.
Firebase Integration
Auth, Firestore, Cloud Functions, push, and analytics, set up to hold under real traffic.
API Integration
REST and GraphQL clients with typed models, caching, and sensible offline behavior.
App Optimization
Finding and fixing the slow frames, oversized builds, and long cold starts with the profiler.
Cross-platform Development
One codebase that runs on iOS, Android, web, and desktop.
Publishing to the App Store & Play Store
Store listings, signing, and review submission — including the back-and-forth until it's live.
