I build mobile applications with Flutter and React Native, connecting the screens people use to the APIs and business logic behind them. I'm Usman Nadeem, a freelance full-stack and AI engineer in Lahore, Pakistan, with 12+ years of product work.
Choose a focused first build, a planned product release or a rescue sprint. Each engagement has a clear scope, reviewable deliverables and a custom quote.
For a new product that needs a clear, testable first release.
Timeline depends on scope, design readiness, integrations and platform requirements.
For teams ready to develop an agreed product release.
Features are split into milestones, with real builds to review rather than a final reveal.
For apps with bugs, slow screens or difficult maintenance.
Start with an audit and a focused fix list. Wider changes are quoted separately.
There is no universal mobile-app timeline. We agree the first milestone after reviewing the screens, backend, devices and release requirements.
Both frameworks can support cross-platform mobile development, but the best choice depends on your team, existing code, interface and device integrations. I work with both and explain the trade-offs before we commit. Target operating systems, minimum versions and supported devices are agreed for your project; a shared codebase still needs platform-specific testing.
Flutter uses Dart and a widget-based UI approach. It is a practical option for teams that want a cohesive interface and a structured shared application codebase. I scope navigation, state management, API access and plugin choices around the actual app, including any native integration work that cannot be assumed to work out of the box.
React Native uses React with JavaScript or TypeScript, which can suit teams already comfortable with that ecosystem. I build reusable components, organise state and server data, and review native dependencies and build requirements early. An Expo-based approach or another build setup is selected only after checking the features and operational needs.
Neither option removes the need for thoughtful design, secure APIs, device testing or release preparation. If a requirement calls for specialist native development, I flag it instead of promising that one framework solves everything.
A polished screen is only part of a working mobile product. Authentication, permissions, data validation, pagination and consistent error handling need to fit the app. I can integrate your existing backend, agree contracts with your team or build the API as part of the engagement. For backend-heavy projects, see Laravel development.
I bring 12+ years of delivery across 500+ projects and 150+ clients, with 95% repeat or referral. You work directly with me from Lahore, Pakistan. I explain what is included, what depends on a third party and what should wait for a later release.
Send your idea, designs or existing app details, plus the platforms you need. I will propose a practical first milestone and a custom quote.
A mobile release needs a working product, a reliable build and a plan for what happens after users install it. These activities are scoped explicitly; compilation alone does not mean an app is ready for customers.
Store review decisions and timing belong to Apple or Google, not the developer. After launch, support and maintenance can be quoted separately.

It depends on your existing team, interface, integrations and maintenance plan. Flutter uses Dart and a widget-based UI approach. React Native uses React with JavaScript or TypeScript. I build with both and recommend after reviewing your product, not before.
The AI Reply, thefood POS and theDukanPOS mobile apps were built with Flutter; TRP Experience was built with React Native.
Flutter and React Native can support both. We agree the target platforms, minimum operating-system versions and device matrix before quoting. Shared code does not remove platform-specific testing or integration work.
Yes. I can connect an existing API, work with your backend team or build the API as part of the engagement. We agree authentication, permissions, data contracts, error handling and compatibility with future app versions.
I implement and refine mobile interfaces from an agreed design. If a new visual system is needed, we plan design collaboration separately so the build starts with clear screens and user journeys.
These can be included after checking the product, platform and service requirements. Offline synchronisation, payment rules, push permissions and third-party SDK constraints need explicit scope; they are not assumed to be included in every app.
Yes. I review the app structure, dependencies, API integration and key problems first, then propose prioritised fixes or upgrades with regression checks around the flows affected.
Submission support is included when agreed in the scope. Developer accounts remain yours. Listing assets, privacy information and required declarations need your input. Apple and Google control approval and review timing; I do not guarantee acceptance or a publication date.
We agree the handoff and any initial fix period in the proposal. Ongoing updates, compatibility work, monitoring and new features can be quoted as separate support and maintenance.
Each project receives a custom quote based on platforms, screens, integrations, existing code and acceptance criteria. Send a brief through the contact form with your design or app status and target timeline. Work is split into clearly defined milestones; there are no fixed prices on this page.
