FAQ
Can you build my app from scratch?
Yes. I can build a custom web application, admin panel, or client portal from the ground up based on your workflow and requirements.
Will I receive the source code?
Yes. Source code is included in every package and can be delivered through GitHub or as a ZIP export. This is a meaningful differentiator because many Fiverr packages treat source code as optional or platform-dependent, while serious code-first sellers often make it explicit.
What do you need before starting?
A brief description of your business goal, required features, user types, design references if you have them, and any existing code or hosting details.
Do you work on existing projects?
Yes, if the codebase and scope are a good fit. Send the stack details and a brief list of required changes before ordering.
Do you use AI tools in development?
Yes, I use an AI-assisted workflow for planning, debugging, and documentation, but I still deliver real code, real version control, and a project structure you can maintain.
What does a revision cover?
A revision covers adjustments to the agreed scope. New features, new pages, or major scope changes require a custom offer or package upgrade.
Are hosting and domain costs included?
No. Hosting, domain registration, paid APIs, subscriptions, plugins, and third-party service fees are paid by the buyer. Deployment can be purchased separately when the selected hosting environment is compatible.
What is considered a page or screen?
A screen is one distinct application view, such as a login screen, dashboard, customer list, form, settings screen, or content-management screen. Popups and minor states do not automatically count as separate screens.
