Flutter mobile app development
Flutter Mobile App Development for iOS and Android
I build cross-platform mobile apps with Flutter, and the backend and APIs behind them, so one developer is accountable for the whole product. Based in Karachi, Pakistan, I work remotely with clients across the USA, UK, Canada, Australia, the Middle East and Pakistan.
Flutter app development by Ahmer Najam
Flutter lets you ship one mobile app to both iOS and Android from a single codebase. For most business and startup apps that means a faster first release and one codebase to maintain instead of two, without giving up a polished, native-feeling interface.
I am Ahmer Najam, a full stack developer and solution architect with more than 20 years of experience in corporate IT. Most mobile apps are only as good as the system behind them, and that is where my experience is strongest: Node.js back ends, REST APIs, databases, dashboards, ERP and CRM. You get the app and the backend it depends on from the same person.
What I build with Flutter
- Custom mobile apps for businesses and startups, for iOS and Android from one codebase
- Companion mobile apps for an existing web platform, portal or dashboard
- Ordering, booking and customer apps connected to your back end
- Field and staff apps that feed data into your ERP or CRM
- Apps that connect to payment, messaging and other third-party APIs
- Release preparation for the App Store and Google Play
The backend and APIs your app needs
A mobile app usually needs accounts, a database, an admin dashboard and secure APIs. I build these with Node.js, REST APIs and MongoDB, and deploy them with Docker, so you do not have to coordinate separate mobile and backend teams.
- REST APIs and authentication for your app
- Admin dashboards and reporting for your team
- Integrations with ERP, CRM, payment and messaging platforms
- Cloud or self-hosted deployment with documentation
Custom mobile app development for startups
For a new product I recommend starting with the smallest version that proves the idea, released to real users, then extending it based on feedback. Flutter suits this well because one build reaches both platforms.
Flutter app development for clients worldwide
I build mobile apps remotely for clients in the USA, the UK, Canada, Australia, the UAE and the wider Middle East, and for businesses in Pakistan. Work is delivered in weekly increments, so you can install and test real builds early.
How a mobile app project works
- Short discovery call on the goal, the users and the must-have features, followed by a clear plan.
- Weekly builds you can install on your own phone and test, so feedback shapes the app early.
- Backend deployment, store release preparation and handoff, with documentation for your team.

Frequently asked questions
Why choose Flutter for a mobile app?
Flutter lets you build for iOS and Android from one codebase, which usually means a faster first release and lower maintenance cost than two separate native apps, while still delivering a smooth, polished interface.
Can you build the backend as well as the app?
Yes. I build the Node.js back end, REST APIs, database and admin dashboard that the app relies on, so you work with one developer instead of coordinating separate mobile and backend teams.
Can you publish the app to the App Store and Google Play?
I prepare the app for release and guide you through submission. The store accounts should be in your own name so that you own the app and its listings.
Do you do custom mobile app development for startups?
Yes. I recommend building a focused first version, releasing it to real users and extending it from feedback. Work is organised in weekly builds you can install and test.
How much does a Flutter app cost?
It depends on the number of screens, user roles, integrations and the back end required. After a short discovery call I give a clear plan and scope. My custom software cost guide explains the main factors.
Where are you based, and do you work with overseas clients?
I am based in Karachi, Pakistan and work remotely with clients worldwide, including the USA, UK, Canada, Australia and the Middle East.
