FAQ
What information do you need to start?
I need your app idea/requirements document, wireframes or sketches (if any), target platforms, and any API specifications or design assets you have.
Which tech stack do you use?
I primarily use Flutter for cross‑platform iOS & Android. For backend I work with Firebase, Node.js/Express, or PHP/Laravel—based on your needs.
How do you handle UI/UX design?
I convert Figma/Sketch/Adobe XD designs into Flutter code, ensuring pixel‑perfect fidelity and responsive layouts.
What’s your development process?
We’ll kick off with requirement analysis → UI/UX mockups → iterative development (milestones) → testing → deployment → 1 year support.
How do you ensure app performance & security?
I implement best practices: optimized state management (GetX), code obfuscation, secure API calls (HTTPS, token auth), and penetration testing.
Will my app be accepted in App Store & Google Play?
Yes—100% App Live Guarantee. I handle provisioning profiles, certificates, play-console setup, and submission guidelines compliance.
What if I’m not satisfied?
Your satisfaction is guaranteed. We’ll iterate until you’re happy, or you can opt for a refund per Fiverr’s terms.
