What sets my approach apart — backed by real production experience, not just theory.
Not just theory — I've shipped 25+ mobile apps to the App Store and Google Play with real users, real revenue, and real ratings. From mindGTC crypto wallet handling blockchain transactions to Laung Elaichi dating app with 50K+ downloads, my work is battle-tested in production environments.
A single React Native or Flutter codebase delivers iOS and Android apps simultaneously, reducing development time by 35–40% and maintenance costs significantly. You get two platforms for nearly the price of one, without compromising on native look, feel, or performance.
I maintain production-grade open-source packages — @codsod/react-native-kit (CLI template with auth flows and API interceptors), @codsod/react-native-chat (chat UI kit), and @codsod/react-native-otp-input — used by developers worldwide. This reflects deep framework knowledge beyond typical application development.
I don't just build the frontend — I architect the entire mobile ecosystem including Node.js backends, RESTful APIs, Firebase services, real-time features with Socket.io, and CI/CD pipelines. One developer, complete visibility, zero coordination overhead.
Bi-weekly sprint demos, daily Slack/Discord updates, shared Jira/Linear boards, and recorded demo sessions. You always know exactly where your project stands, what's in progress, and what's coming next. No surprises, no black boxes.
Every app I build follows clean architecture principles — feature-based modules, dependency injection, proper separation of concerns, and comprehensive documentation — making it easy to scale the codebase and onboard additional developers as your product grows.
Common questions about my mobile app development services — pricing, timeline, process, and more.
Mobile app development costs vary significantly based on complexity. A simple MVP with 5–8 screens typically ranges from $3,000–$8,000. A mid-complexity app with user auth, payments, and real-time features runs $8,000–$25,000. Enterprise-grade apps with complex integrations start from $25,000+. I provide detailed fixed-price quotes after the discovery phase so there are no surprises.
A focused MVP can be shipped in 6–10 weeks. A fully-featured production app typically takes 3–6 months depending on complexity, number of integrations, and testing requirements. I provide a detailed sprint-level timeline during the discovery phase with clear milestones, and you see working builds every two weeks throughout development.
Both are excellent cross-platform frameworks. React Native is my primary recommendation for most business apps — it has a larger ecosystem, uses JavaScript/TypeScript (easier to find talent later), and allows native module integration when needed. Flutter is better for visually complex apps needing highly customized animations. I also recommend going fully native (Swift/Kotlin) for apps needing deep platform integration like AR, health tracking, or complex camera features.
Native development (Swift for iOS, Kotlin for Android) means building separate codebases for each platform — maximum performance but double the cost and timeline. Cross-platform frameworks like React Native and Flutter let you write one codebase that runs on both platforms with 85–95% code sharing, reducing costs by 35–40% while maintaining near-native performance. For most business applications, cross-platform is the smart choice.
Yes — I manage the complete store submission lifecycle including Apple Developer and Google Play Console account setup (if needed), app signing, metadata and keyword optimization, screenshot and preview video generation, staged rollout configuration, and review compliance. I also handle any rejections and resubmissions, so you don't need to worry about platform-specific policies.
Absolutely. I regularly integrate mobile apps with existing REST APIs, GraphQL endpoints, Firebase services, AWS backends, and third-party services like Stripe, Twilio, SendGrid, and social auth providers. If you don't have a backend yet, I can build one using Node.js/Express as part of a full-stack engagement.
Yes, I offer ongoing support packages covering crash monitoring with Firebase Crashlytics, performance analytics, OS compatibility updates (new iOS/Android versions), security patches, bug fixes, and feature iterations. I also provide CodePush integration for instant over-the-air bug fixes without requiring a full store review cycle.
Security is built into every layer — SSL/TLS for all network communications, secure token storage in iOS Keychain and Android Keystore, biometric authentication, certificate pinning to prevent MITM attacks, code obfuscation, ProGuard/R8 for Android, and OWASP Mobile Top 10 compliance. For fintech apps, I implement additional measures like jailbreak/root detection and transaction signing.
Yes, I develop companion apps and standalone experiences for Apple Watch (watchOS) and Wear OS. Common use cases include health/fitness tracking with HealthKit/Google Fit sync, notification handling, quick actions, and data synchronization between phone and wearable devices.
You receive 100% ownership of all source code, design files, and intellectual property.
