Does your application have multiple user types, private records, uploads, or dashboards that must not expose the wrong information?
I will review and repair the Supabase access model so that authentication, roles, database policies, Storage permissions, and application logic agree with each other.
Typical use cases
- Customers, staff, vendors, dealers, students, or administrators with different permissions.
- Users who should see only their own records.
- Public users who can read approved content but cannot write private data.
- Admin dashboards with controlled management actions.
- Private customer photos, documents, or files.
- Supabase Auth sessions and OAuth redirects.
- RLS policies that block valid requests or allow unauthorized access.
- Database functions, API endpoints, and Edge Functions that need safer authorization.
- Existing AI-generated apps where frontend controls exist but backend policies are incomplete.

I help founders and businesses turn AI-generated prototypes into reliable, testable products.
I build and repair web apps, SaaS MVPs, dashboards, customer portals, internal tools, and business automations using React, Next.js, TypeScript, Supabase, PostgreSQL, Vercel, GitHub, n8n, and modern AI development workflows.
My work is especially useful when an app works in preview but fails in production, when Supabase Auth or RLS permissions are misconfigured, when a deployment is broken, or when manual business processes need to connect through APIs, webhooks, CRM tools, and AI workflows.
FAQ
Can you create RLS policies for public and authenticated users?
Yes. I can implement rules such as public read access for published records and authenticated owner-only write access, provided the required business logic is defined.
Can you fix an AI-generated Supabase app?
Yes. I can review the database policies, client queries, Auth flow, and related server functions in an existing project.
Will you guarantee that my whole app is secure?
The package covers the defined scope. A complete application security assessment requires explicit coverage of infrastructure, dependencies, application logic, authentication, data, and operational controls.
Can you protect private uploads?
Yes. I can review bucket policies, file paths, signed URLs, ownership rules, and access checks within the selected scope.
