FAQ
Do you develop for both iOS and Android?
Yes. I specialize in Flutter, which allows me to create a single codebase that works perfectly on both iOS and Android.
Will you help with the App Store and Play Store submission?
Absolutely. Developing the app is only half process, I will guide you through the entire deployment process, including setting up your developer accounts, preparing assets, and ensuring the app meets all guidelines to pass the review process on both the Apple App Store and Google Play Store
How much time would you take to develop my app?
The timeline is defined based on the scope of the project. I will take a minimum of 5 days and a maximum of 21 days for large-scale apps.
Who owns the source code once the project is finished?
You do. Once the final payment is cleared, I provide the full source code and all related assets.
Can you integrate AI or custom APIs into my app?
Yes. I have extensive experience integrating REST APIs, Firebase, and advanced features like AI Chatbots or agentic workflows.
What do I need to provide to get started?
To give you the most accurate quote, it’s helpful to have a brief description of your app’s core features, any design inspirations or wireframes, and your preferred timeline. If you’re not sure where to start, send me a message. I’m happy to consult with you to figure out the requirements
Do you provide post-launch support?
Yes. I don’t just "code and go." I offer a support period after the app is launched to ensure everything is running smoothly.
Why should I hire you instead of a cheaper agency?
When you hire me, you are working directly with a Senior Full-Stack Architect with over 7 years of experience. I provide a consultative approach, meaning I don't just follow instructions. I suggest improvements to make your app more successful. You get corporate-level reliability in person.
