Over deze dienst
Users cannot log in, paid features stay locked, bookings disappear or form submissions never reach your dashboard?
I fix Lovable and Base44 apps by repairing the workflows your customers and team rely on.
WHAT I CAN FIX:
- Supabase login, signup, OAuth and session errors
- Stripe checkout, subscriptions and webhook failures
- Payment status sync and paid-content access
- User roles, Supabase RLS and customer data isolation
- Forms not saving and missing dashboard records
- Booking creation and appointment visibility
- Provider availability and scheduling workflows
- Booking emails, reminders and notifications
- Stripe Connect onboarding and provider payouts
- Base44 forms connected to CRM lead capture
- Round-robin lead assignment and follow-up reminders
- Admin dashboards and staff permissions
- API connections and failed backend functions
- Mobile layouts, broken buttons and navigation
- Deployment errors and custom domain setup
- Agreed SaaS MVP features and launch testing
Supabase fixes apply where your app uses Supabase. Each order covers agreed features, testing and handover notes.
Message me your app link, broken workflow and exact expected result for a scoped quote.

I turn Base44 and AI-built apps into maintainable React Native and Expo mobile applications powered by Supabase.
My services cover frontend development, backend development, full stack software development, PostgreSQL databases, Supabase Auth, API integration, bug fixing, app migration, and iOS/Android build preparation.
I focus on clean code, responsive interfaces, reliable functionality, careful testing, and clear communication.
Whether you need to rebuild an MVP, migrate a backend, or fix an existing application, I will review your requirements and provide a clear development plan

Veelgestelde vragen
Can you fix an app I already built with Lovable or Base44?
Yes. I review your existing app, reproduce the problem and repair the agreed features. Send the app link, error details and expected behavior so I can assess the work before you order.
Can you fix Supabase login and signup errors?
Yes. For apps using Supabase, I can troubleshoot authentication, Google OAuth, password resets, email verification, session issues and redirects. I test the agreed login flow after making changes.
Can you fix Stripe payments that do not unlock paid features?
Yes. I can investigate checkout, webhooks, subscription status and paid-user access. The scope depends on your current payment setup and the specific behavior that needs correcting.
Can you fix user roles and Supabase RLS policies?
Yes. I can review agreed roles and database permissions, correct identified access problems and retest them with appropriate test accounts. A full security audit is a separate service.
Can you finish my unfinished SaaS MVP?
Yes. Send your remaining feature list and current blockers. I can quote for agreed MVP completion tasks, including forms, dashboards, backend workflows and integrations. Full completion is assessed separately from bug-fix packages.
My app works in preview but fails when published. Can you help?
Yes. I can investigate build errors, environment settings, API connections, redirects and deployment failures. Please share the hosting platform, relevant logs and steps that trigger the problem.
Can you repair API integrations and backend functions?
Yes. I can troubleshoot failed API requests, backend functions, database connections and data-saving problems. Please provide the API documentation and explain the expected workflow.
Does every Base44 project require Supabase?
No. I review the backend your app actually uses. Supabase services apply to projects connected to Supabase; Base44 repairs are scoped around your existing setup and supported integrations.
