Veelgestelde vragen
Can you fix Supabase RLS policy errors?
Yes. I can diagnose and fix Supabase Row Level Security issues including permission denied errors, incorrect auth.uid() conditions, missing policies, overly permissive policies and users accessing the wrong rows. I also test the resulting access rules.
Can you fix users seeing other users' data?
Yes. This is a common multi-user/RLS problem. I can review your database relationships, authentication context, grants and RLS policies and implement proper user-level or role-based data isolation.
My Supabase query returns an empty array. Can you fix it?
Yes. Empty results can occur when RLS is enabled without the correct policy, when the authenticated session is missing, or when database grants don't permit the requested operation. I will diagnose the actual cause rather than simply disabling RLS.
Can you secure a Lovable, Bolt or Replit app?
Yes. I can review AI-built applications using Supabase/PostgreSQL for RLS, authentication, authorization, database permissions, exposed data, API access and backend configuration issues.
Can you fix Supabase authentication?
Yes. I can troubleshoot signup, login, sessions, OAuth, protected routes and authentication-related database/RLS problems where they are within the project's technical scope.
Can you fix PostgreSQL database problems?
Yes. I can troubleshoot PostgreSQL queries, permissions, schema relationships, RLS-related problems, database access errors, performance issues and backend/database integration problems.
Can you audit my Supabase database before launch?
Yes. I can perform a technical security review covering RLS, authentication, authorization, permissions, exposed database objects, backend access and other configuration risks, then provide prioritized remediation steps.
Do you perform a penetration test?
This gig is primarily a Supabase/PostgreSQL security and configuration audit, not a formal penetration test, certification or compliance audit. If you require a specific security-testing scope, contact me first so I can confirm whether it is appropriate.
Can you fix RLS without breaking my application?
Yes. The goal is to enforce the correct authorization rules while preserving legitimate application functionality. Changes should be tested against the application's required user roles and database operations.
Can you set up role-based access control?
Yes. I can implement or troubleshoot role-based access patterns such as admin, manager, staff and regular-user permissions using Supabase Auth, PostgreSQL and RLS where appropriate.
