About this gig
Your Lovable or Base44 app looks great in preview, but login fails, Stripe checkout breaks, or deployment won't go live? Don't let one bug derail your launch.
I troubleshoot AI-built web apps and SaaS MVPs, pinpoint the cause, and repair the agreed issues without an unnecessary rebuild.
WHAT I CAN FIX:
- Lovable bugs, broken buttons, forms, routing and blank screens
- Supabase auth errors, signup/login, OAuth and database connections
- Stripe Checkout errors, payment redirects and webhook issues
- API integration failures and frontend/backend mismatches
- Base44 app glitches, publishing and supported integrations
- Vercel, Netlify, custom domain and deployment errors
WHAT YOU GET:
A clear diagnosis, targeted fixes, testing of affected features, and documentation where included. You'll know what changed and how to check it.
From a single UI fix to a scoped Supabase or Stripe repair, or a Lovable app launch, choose the package that matches your issue. New features and complex integrations are quoted separately.
ORDER or MESSAGE ME before ordering with your app link, error screenshot and desired outcome. I'll review the scope and recommend the right next step with a clear, practical plan.

I develop AI-powered business tools that solve practical problems, from n8n workflow automation and Shopify integrations to custom chatbots, API connections, and web or mobile app features. I focus on clear requirements, reliable data flows, testing, and useful documentation rather than one-size-fits-all setups. Services can include CRM sync, order and inventory workflows, document-based AI assistants, and tailored business applications. Tell me about the process you want to improve, and we can define a realistic solution and scope.
FAQ
Can you fix bugs in both Lovable and Base44 apps?
Yes, I troubleshoot Lovable and Base44 web apps, including broken buttons, forms, login errors, API issues, database connections, and deployment problems. I'll review your specific issue and recommend the right solution.
Can you fix Lovable Supabase authentication and database errors?
Yes. I can troubleshoot Supabase login, signup, OAuth, database connections, and permission-related errors. The scope depends on the issue and your selected package.
Can you fix Stripe payment errors or integrate Stripe Checkout?
Yes, I can troubleshoot Stripe Checkout failures, payment redirects, and supported webhook issues. The Premium package includes a basic Stripe Checkout integration. Complex subscriptions and advanced payment systems require a custom quote.

Yes. I can assist with supported deployment environments, publishing problems, environment configuration, and domain connections. Deployment is included in Premium, provided your application and hosting are ready.

Not necessarily. My priority is to diagnose and repair the affected functionality while preserving your existing application. If substantial restructuring is necessary, I'll explain the additional work before proceeding.
Which package should I choose for my Lovable app?
Basic covers one small UI or form issue. Standard covers two minor bugs or one defined Supabase, database, or Stripe repair. Premium includes up to three small fixes, basic Stripe Checkout integration, and deployment.
What do you need to start fixing my AI web app?
Please provide your app link, a description of the issue, relevant error screenshots, and your expected result. After the order begins, I may request secure, limited-permission access. Please never send passwords or private API keys through Fiverr messages.
