I will fix supabase authentication, rls or API integration issues
Mattia Turconi
About this gig
I will diagnose and repair a clearly scoped Supabase or REST API integration problem in an existing application.
Supported areas include Supabase Auth sessions and redirects, PostgreSQL queries, Row Level Security policies, data-access errors, Edge Function or REST API failures, and frontend/backend integration issues in JavaScript or TypeScript projects.
Every package includes focused diagnosis, an implemented correction, relevant checks in a safe environment and concise change notes. Standard covers one medium issue or two related small issues in one flow. Premium covers one bounded application flow and adds targeted RLS checks for the affected tables and roles.
This is not a certified security audit or compliance assessment. Full backend rebuilds, destructive production migrations, payment systems, unrelated features, hosting and ongoing monitoring are excluded.
Please contact me before ordering if production data, several flows or unclear access rules are involved. Staging and synthetic data are preferred. Never send passwords or service-role keys in Fiverr messages, and I will not disable RLS as a shortcut.

I'm an independent software developer and university student behind Modern Software Solutions. I work with JavaScript, TypeScript, React, React Native, Expo, Supabase, PostgreSQL and REST APIs. My projects include VisitorFlow, a QR-based visitor management app, and AI Mobile Starter Kit, a mobile app template. I focus on clear scope, practical debugging, code reviews and small automations, and use AI-assisted development tools where appropriate. Tell me what you need to fix or simplify, and we can agree on a focused deliverable.

Yes. Describe the issue, expected result and relevant technology through Fiverr before ordering. We can confirm whether the Basic package fits. Larger or uncertain work needs a custom offer through Fiverr.
What does one revision include?
One revision addresses feedback on the agreed deliverable within the original scope. New requirements or unrelated issues need a separate agreement.
Does this include a full backend setup?
No. Basic covers one identified issue in an existing integration. A complete backend, complex migration, production environment setup or certified security audit is outside this package.
Does this include a full backend setup?
