FAQ
Which AI coding tools do you support?
Cursor, Lovable, Bolt, Replit, Claude Code, v0, and other tools that generate web applications. I can assess your existing codebase before confirming compatibility.
Can you work on an existing project rather than rebuild it?
Yes. I prefer to inspect and improve your existing application, preserving working features wherever practical.
Can you connect a frontend to a backend or database?
Yes. I can build or repair APIs, integrate databases, implement authentication, and connect third-party services.
Can you deploy my application?
Yes. Deployment assistance is included in the Premium package within the agreed scope. Hosting fees and paid third-party services are separate.
Can you build a complete application from scratch?
Yes, but a complete application is usually best handled through a custom offer after discussing its features, complexity, and requirements.
Should I order before contacting you?
For complex applications, please message me first. I will review your requirements and recommend the appropriate package.
