Senior Flutter Developer | Android & iOS Apps, MVPs, App Rescue, Firebase/API Integrations & Store Launch Support

I am a Senior Flutter Developer with 5+ years of experience building, fixing, launching, and maintaining production mobile apps for Android and iOS.

I work with founders, startups, agencies, and product teams that need more than basic app development. My focus is on reliable mobile products with clean architecture, stable releases, scalable integrations, smooth performance, and long-term maintainability.

My core expertise is Flutter and Dart, supported by strong native mobile experience in Android, iOS, Kotlin, Swift, and Kotlin Multiplatform. This allows me to handle complete mobile app development as well as complex platform-specific issues, release blockers, integrations, and long-term app support.

Over the years, I have worked on 15+ production apps and supported apps with 200K+ installs across Android and iOS. My experience includes utility apps, travel apps, trading tools, e-commerce apps, subscription-based apps, Firebase/API-powered apps, and NDA client products.

Core services include:

1. Flutter MVP development for Android and iOS
2. Full Flutter mobile app development
3. Existing app rescue and codebase improvement
4. Bug fixing, crash fixing, and build issue resolution
5. Firebase, REST API, WebSocket, and third-party SDK integrations
6. AI features, payment gateways, subscriptions, and in-app purchases
7. Google Play Store, Apple App Store, and TestFlight release support
8. App maintenance, performance optimization, and long-term support
9. Native Android, iOS, and Kotlin Multiplatform support when needed

I am especially useful for clients who already have an app idea, design, existing codebase, or unfinished project and need a developer who can take ownership, identify risks, make technical decisions, and move the app toward a stable release.

My working approach is structured and transparent. I start by understanding the business goal, users, current technical situation, app requirements, and launch priorities. Then I break the work into clear milestones, communicate progress regularly, and deliver reviewable builds so the project status stays clear at every stage.

I do not focus only on writing code. I focus on building mobile apps that are stable, maintainable, release-ready, and useful for real business needs.

For a new MVP, existing app rescue, integrations, store launch, or long-term maintenance, share the project requirements through Guru and I will review the scope and suggest the best next step.

Work Terms

I work on fixed-price, hourly, part-time, and long-term mobile app projects for Android and iOS.

Communication:
Preferred communication is through Guru messages. For detailed discussions, Zoom, Google Meet, or WhatsApp may be used when needed. I provide clear updates, ask key questions early, and keep communication professional.

Project Start:
Before work begins, I review the project requirements, designs, existing codebase, APIs, Firebase setup, store status, bug list, or release issue. After review, I define the scope, timeline, milestones, and delivery plan.

For existing or unfinished apps, a technical review may be required first to check code quality, bugs, build errors, dependencies, API issues, performance risks, and release blockers.

Payment Terms:
I prefer Guru SafePay with milestone-based payments. Larger projects should be divided into clear milestones such as planning, UI, feature development, API/Firebase integration, testing, release build, and store submission support.

For ongoing maintenance, hourly work or monthly retainers are preferred depending on scope and availability.

Revisions:
Minor revisions are included within the agreed scope. New features, major design changes, extra screens, extra integrations, third-party changes, or scope changes are estimated separately.

Delivery:
Deliverables may include Flutter source code, Android/iOS builds, Firebase/API integrations, bug fixes, release builds, app store support, documentation notes, and maintenance support, based on the agreed scope.

Confidentiality:
Client ideas, source code, credentials, APIs, designs, business information, and project assets are treated as confidential. NDA work is accepted when required.

Long-Term Support:
Ongoing support is available for maintenance, bug fixing, performance improvements, dependency updates, new features, Play Store/App Store release support, and product improvements after delivery.
