Frequently Asked Questions

If you need a quick bug fix, start with Basic. For adding features or UI cleanup, go with Standard. If your MVP is broken, complex, or across tools (e.g. GPT + Replit + Stripe), choose the Premium Rescue package. Still unsure? Just message me!

Yes — many clients need urgent fixes before a pitch, demo, or launch. I offer 48-hour delivery add-ons for Premium orders and can prioritize your project if needed. Please message me first so we can plan around your deadline and scope.

Vibe coding means using AI tools like GPT-4 to generate app code from prompts — fast but often messy. I specialize in fixing these AI-generated MVPs, rewriting unstable sections, and finishing what the AI couldn’t, so you have a clean, reliable product.

Yes! I help founders who started building with AI tools like Lovable, Replit, Bolt, or Base44 and are now stuck with broken features, bugs, or deployment issues. I’ll review the project, clean the code, and make your MVP fully functional and ready to launch.

Absolutely. I can develop and integrate key features your AI-generated app needs — including user authentication, payment gateways like Stripe, dynamic dashboards, GPT flows, API connections, and database integrations like Firebase or Supabase.

Yes, I can clean up poorly structured or auto-generated layouts and implement a modern UI using React, Next.js, and Tailwind CSS. I ensure your app looks great on desktop and mobile, and feels professional enough for users, investors, or live demos.

Yes, all deliveries include 100% clean source code. For Standard and Premium packages, I also provide a walkthrough document or video guide explaining what was fixed or added, how the app works, and how you can manage or scale it going forward.

Of course! Just send your code link, GitHub repo, Replit project, or screenshots. I’ll give you a free initial review to explain what’s working, what’s broken, and what your app needs. You’ll only pay once you know I can deliver exactly what you need.

Yes. I regularly work with Firebase, Supabase, GPT-4 API, Langchain, Vercel, and Netlify. Whether it's backend integration or full-stack fixes, I’ll connect everything properly and help you deploy the finished app to production.

Yes! I can help integrate and debug custom GPT flows, AI logic, and chatbot-like functionality in your app — especially if you started with tools like Bolt, Replit, or Lovable and need help wiring up the GPT responses to your UI or backend.
