FAQ
Can you diagnose Base44 app bugs without rebuilding my existing MVP?
Yes. I inspect browser errors, Base44 logic, API responses, database rules and recent changes first. My bug fixing process targets the root cause, protects working features and avoids an unnecessary rebuild.
Do you repair Base44 authentication, database and API integration failures?
Yes. I can troubleshoot OAuth redirects, login loops, role permissions, Supabase or Firebase rules, REST API integration, webhooks and failed data requests. Access must be provided through secure project invitations.
Can you complete a Base44 migration without losing users or database records?
Yes, when the source platform allows export or transfer. I map the schema, authentication, files, environment variables and integrations before app migration. I create a backup and test critical records before launch.
Can you migrate a Lovable app or Replit app into a maintainable project?
Yes. I can review the current code, dependencies, routes, backend services and deployment settings. The migration scope depends on code access, platform limits and whether the existing Lovable app or Replit app works correctly
Can you configure a Capacitor app for Android and iOS mobile builds?
Yes. I can set up Capacitor, package identifiers, icons, splash screens, permissions and native build settings. A Capacitor app must first have a stable responsive web version before mobile conversion and device testing.
What technical checks are included before app deployment?
I verify build commands, environment variables, API endpoints, authentication callbacks, routing, database access and production errors. App deployment can cover Vercel or another supported host agreed before the order.
Can you fix webhooks and third-party services in a Base44 integration?
Yes. I test request methods, headers, payloads, authentication tokens, callback URLs and error responses. Base44 integration work can cover supported REST APIs, payments, email tools, automation and external databases.
How do you test bug fixing, mobile app fix and migration work?
I reproduce the issue first, apply the fix, retest the affected flow and run regression checks on related features. For a mobile app fix, I also check responsive layout, navigation, permissions and supported device behavior.
Can you improve an existing SaaS MVP instead of starting new MVP development?
Yes. I can stabilize an existing SaaS MVP, repair features, improve performance and prepare it to deploy. MVP development additions are estimated after reviewing the feature list, data model and current project condition.
Can you audit an undocumented Base44 or vibe coding project?
Yes. As a Base44 expert, I can trace pages, entities, automations, APIs and dependencies in a vibe coding project. I will explain the findings, risks and recommended scope before making major changes.
