FAQ
Do you work on iOS and Android equally?
Yes! I specialize in Flutter for cross-platform development (one codebase, both platforms). I also do native iOS (Swift) and Android (Kotlin) separately if preferred. Most clients choose Flutter to save 40% on costs.
Will you handle app store submission?
Absolutely! I manage the entire submission process to Apple App Store and Google Play Store, including creating app screenshots, descriptions, keywords, and responding to review feedback.
Can you integrate AI features like ChatGPT?
Yes! I integrate OpenAI's ChatGPT, Claude, Gemini, and custom AI models. I handle API keys securely, implement cost optimization (token management), and create intelligent chatbots, content generators, and automation tools.
Do I own the source code?
100% YES. You receive complete, commented source code in GitHub. You can use it forever, modify it, or hire another developer. No recurring licensing fees—it's yours to keep.
What's your process? How do we stay in sync?
Consultation — Understand your vision, features, timeline Wireframes — Design app flow and UI layouts Development — Build in sprints with weekly demos Testing — QA, bug fixes, optimization Launch — Submit to app stores, hand over code Support — 30 days of free maintenance
What if the app idea is complex or custom?
Perfect! That's my specialty. Complex features (real-time chat, maps, payments, blockchain, AR, ML) are all possible. I'll provide a custom quote after understanding requirements. Message me BEFORE ordering for custom scope.
Can you build an app like [competitor's app]?
Yes, I can build apps inspired by Uber, Instagram, Airbnb, TikTok, etc. with your unique features. I'll NOT copy code (that's illegal), but I can recreate functionality with clean, original code. Discuss features first so I can quote accurately.
