FAQ
What do I need to provide to get started?
You can provide Figma/Adobe XD designs, wireframes, or simply a written list of features and requirements. If you only have an idea, message me first—we can discuss your vision and define the technical roadmap together.
Can you develop an app for both iOS and Android?
Yes! Using React Native and Expo, I build cross-platform mobile apps with a single codebase. This ensures seamless performance, native feel, and consistent UI on both iOS and Android while saving development time and cost.
Will you help deploy my web application or mobile app to live stores?
Absolutely. I handle end-to-end deployment, including cloud hosting on AWS/Google Cloud/Vercel for web apps and backend services, as well as preparing production builds and assisting with publishing to the Google Play Store and Apple App Store.
Do you provide custom backend API and database development?
Yes. I build secure, scalable backends using Node.js, Express, or Hono, integrate databases like PostgreSQL or MongoDB, and implement robust authentication (JWT, RBAC) alongside third-party APIs (such as payment gateways like Stripe).
Do you offer support or maintenance after the project is completed?
Yes, I provide post-delivery support to ensure everything runs smoothly in production, fix any unexpected bugs, and help you get settled with your new web or mobile platform. Longer-term maintenance can also be arranged.
