Yes. I will review the existing application before making changes, identify the areas that need improvement and work within the agreed scope. I can repair bugs, improve the interface and add features while checking existing functionality.
Can you connect my custom domain and prepare my Base44 app for launch?
Yes. I can help configure your custom domain, investigate deployment and DNS issues, test important app functions and prepare the application for launch. Hosting or domain-provider access may be required.
Can you fix Base44 workflows, automations and custom functions?
Yes. I can troubleshoot failed triggers, incorrect conditions, broken actions and custom-function errors. I will trace the affected workflow, correct its logic and test the process against your expected outcome.
Can you build a SaaS MVP or custom web application with Base44?
Yes. I can help develop a Base44 SaaS MVP or custom web app with features such as user accounts, dashboards, subscription flows, database functionality and admin controls. The scope will be agreed before development.

Yes. I can investigate authentication errors, failed signups, login redirects, user sessions and access permissions. I will work on the affected configuration and test the user flow to ensure accounts work as intended.
Can you connect an external API or Supabase to my Base44 application?
Yes. I can connect supported third-party APIs or Supabase, configure the required authentication and data exchange, and troubleshoot failed requests so your app can communicate properly with external services.

Yes. I can inspect your existing Base44 app, identify the cause of broken buttons, failed workflows, loading issues or unexpected errors, then repair the affected functions and test the fixes.
