About this gig
Need one professional mobile app that works on both Android and iOS?
I am a senior mobile engineer with 8+ years of experience building production applications for telecom, fintech, commerce, GPS, healthcare, and consumer platforms.
- I develop cross-platform Flutter applications using Dart, clean architecture, responsive UI, and maintainable code.
- I can help you with:
- Flutter app development for Android and iOS
- Figma or Adobe XD to responsive Flutter UI
- REST API and Firebase integration
- Authentication and user management
- Payments, maps, and location services
- Push notifications and analytics
- Local storage and offline functionality
- Bug fixing and performance optimization
- Play Store and App Store release assistance
You will receive clean Dart source code, a clearly defined scope, realistic estimates, regular progress updates, and production-focused testing.
Packages cover clearly scoped Flutter MVPs. Complex backends, advanced integrations, or larger applications require a custom offer.
Please message me before ordering with your features, designs, API details, and preferred deadline so I can recommend the correct package.

FAQ
Can you build both Android and iOS apps from one Flutter project?
Yes. Flutter supports a shared Dart codebase for Android and iOS. Platform-specific configuration may still be required for features such as payments, notifications, maps, and store submission.
Can you convert my Figma design into Flutter?
Yes. Please provide the Figma file and identify all required screens, states, dialogs, and interactions.
Can you improve an existing Flutter application?
Yes. I can add features, resolve bugs, modernize the architecture, improve UI, integrate APIs, and optimize performance.
Is backend development included?
REST API or Firebase integration can be included according to the package. A completely new custom backend is estimated separately.
Do you include source code?
Yes. Clean Dart source code for the agreed scope is included with every package.
Can you publish the application?
Play Store and App Store submission assistance is available in Premium or as an extra. You must provide active developer accounts, legal content, and required store information. Store approval is controlled by Google and Apple.
Do you provide post-delivery support?
I fix defects related to the agreed delivered scope during the support period stated in the order. New features or third-party service changes require a separate order.
Should I order before contacting you?
Please message me first. Price and delivery depend on screen count, backend availability, integrations, designs, and application complexity.
