FAQ
Can you fix my existing Base44, Lovable, Replit, or Bolt app?
Yes. I can troubleshoot bugs, broken features, database errors, API issues, authentication problems, and incomplete functionality in your existing AI-built app.
Can you integrate Stripe, Supabase, or third-party APIs?
Yes. I can integrate Stripe payments, Supabase databases, authentication, APIs, webhooks, email tools, and other third-party services into your app.
Can you complete an unfinished AI-built app?
Absolutely. If your Base44, Lovable, Replit, or Bolt project is partially built, I can fix existing issues, complete missing features, improve the UI, and prepare it for launch.
Can you fix Stripe payments that aren't unlocking features?
Yes. I can troubleshoot Stripe Checkout, webhooks, metadata, subscriptions, and account access so successful payments trigger the correct features or user permissions.
Can you deploy my AI-built web app?
Yes. I can help with domains, production setup, deployment, and launch preparation. I can also help prepare web apps for mobile deployment where applicable.
Do you work with platforms besides Base44?
Yes. Base44 is a key specialty, and I also work with Lovable, Replit, Bolt.new, Supabase, Cursor, Claude Code, v0, and other AI-powered development tools.
Will you work with my existing project without rebuilding everything?
Yes. I first review your existing project and focus on fixing or improving what is already there whenever possible, helping you avoid unnecessary rebuilding and wasted AI credits.
Should I contact you before placing an order?
Yes, especially for larger or unfinished projects. Send me your project link, the issues you're experiencing, and what you want to achieve. I'll review the scope and recommend the right package.
