FAQ
Should I contact you before placing an order?
Yes, especially for Standard or Premium orders. Send me a brief description of the issue, screenshots or error messages, and the platform or technologies used. I will review the problem and recommend the right package before you order.
What is considered a small bug in the Basic package?
The Basic package covers one small, clearly defined issue, such as a broken button, form error, minor UI problem, simple validation issue, or similar isolated bug. Authentication, database, API, deployment, or multiple related issues may require a higher package.
Do you only work with Lovable apps?
No. Lovable is one of the main platforms I support, but I can also review web applications created with other AI-assisted or vibe coding tools. Send me your project details before ordering and I will confirm if I can help.
What access or information will you need?
It depends on the issue. I may need access to the source code, repository, error messages, or relevant configuration. Database and API issues may require additional details. Never send passwords or sensitive credentials in the initial message.
Can you fix Supabase, authentication, database, or API issues?
Yes. I can troubleshoot many issues involving Supabase, databases, authentication flows, REST APIs, frontend/backend communication, and related integrations. Because complexity varies, please contact me before ordering these types of fixes.
Can you complete or add new features to my AI-built application?
Yes, depending on the scope. This Gig is primarily focused on troubleshooting and improvements, but I can also implement additional features. Larger changes or full application development will require a custom offer after reviewing your requirements.
