FAQ
What do you need from me to get started?
I’ll need your app idea, reference designs (if any), required features, and preferred color scheme or branding details. If you already have an API or backend, please share the documentation or access info.
Will my app work on both Android and iOS?
Yes! I build apps with React Native, which allows me to use one codebase for both Android and iOS, saving time and cost while ensuring native-like performance.
Can you integrate my backend or build one from scratch?
Absolutely. I can integrate your existing backend (API) or develop one for you using FastAPI or Node.js, complete with authentication, database, and admin dashboard if needed.
Do you publish the app to the Play Store or App Store?
Yes, I can help with publishing on both platforms under your developer accounts, ensuring your app meets all store requirements.
What if I don’t have a design or UI ready?
No problem! I can create a clean and user-friendly design for you, or work from wireframes and ideas you provide.
Can you add features later after the initial delivery?
Yes, I offer post-launch updates and feature additions as part of separate milestones or custom orders.
Will I get the source code after completion?
Yes, the complete source code and project files are included in all packages once the final payment is made.
