I provide senior-level Flutter app development and app rescue services for Android and iOS mobile apps.
This service is for founders, startups, agencies, and app owners who need a reliable Flutter developer to build a new app, continue an unfinished project, fix an existing app, connect backend services, or prepare the app for Play Store and App Store release.
I have 5+ years of mobile app development experience, with 15+ production apps shipped and 200K+ installs supported across Android and iOS. My core expertise is Flutter and Dart, supported by native Android, iOS, Kotlin, Swift, Kotlin Multiplatform, Firebase, REST APIs, payment integrations, subscriptions, and app release workflows.
This service is suitable for:
- New Flutter MVP development
- Existing Flutter app rescue
- Bug fixing and crash fixing
- Build errors and dependency issues
- Firebase and REST API integrations
- Payment gateway, subscription, and in-app purchase setup
- Play Store, App Store, and TestFlight release support
- Performance improvements and app maintenance
- Native Android/iOS support where required
My process:
First, I review the project requirements, designs, existing codebase, API details, Firebase setup, store status, or bug list. After review, I define the scope, risks, timeline, and recommended milestones.
For existing apps, a technical review may be required before final estimation. This helps identify code quality issues, broken dependencies, build errors, API problems, performance risks, and release blockers.
Deliverables may include:
- Flutter source code updates
- Android and iOS app builds
- New app screens and features
- Bug fixes and crash fixes
- Firebase or REST API integration
- Payment/subscription integration
- Performance improvements
- Play Store or App Store release support
- Technical notes or handover details
- Ongoing maintenance support if agreed
Included:
- Clean Flutter/Dart development
- Android and iOS support
- Clear milestone-based delivery
- Professional communication through Guru
- Reviewable builds during development
- Basic testing for delivered scope
- Release-focused implementation
Not included unless agreed separately:
- UI/UX design from scratch
- Backend development from scratch
- Admin panel development
- Paid third-party accounts or APIs
- Store developer account fees
- Major scope changes after agreement
- Unlimited revisions outside agreed scope
This service is best for clients who want stable mobile development, clear communication, and a production-focused approach instead of quick low-quality coding.
For a new MVP, unfinished app, broken Flutter project, integration task, or launch issue, share the project details through Guru and I will review the scope before starting.
