About this gig
Is Supabase breaking your app? Login failures, RLS permission errors, missing data or backend bugs can stop an otherwise promising project.
I'm a full-stack developer working with Supabase, PostgreSQL, React and Next.js. I troubleshoot, configure and improve Supabase backends for AI-built apps (Lovable, Bolt, Cursor, Replit and more), SaaS products and custom web apps.
WHAT I CAN HELP WITH:
- Authentication: signup, login, OAuth, sessions and password resets
- Row Level Security (RLS): policies, permissions and data access
- PostgreSQL: tables, relationships, SQL queries and migrations
- Edge Functions, RPC, triggers, APIs and webhooks
- Storage, Realtime and frontend integrations
- Supabase project setup and configuration
I investigate the cause, implement the agreed fix or setup, and test the affected flows. I can work in your project or deliver code and clear implementation steps.
Each package covers an agreed scope, not unlimited bugs or a full backend rebuild.
Please message me with your issue and project stack before ordering so we can choose the right scope.

I am Alex, a freelance software engineer based in Turin, Italy, with a computer science degree and six years of client work.
Shopify is where most of my 88 five-star reviews come from: custom code and sections, theme and app fixes, Remix apps, and hand-coded storefronts. I also build full web platforms end to end — Next.js, React, TypeScript, Python, Supabase — and AI systems on top of them, from small n8n automations to document analysis and reporting platforms.
Tell me what you are trying to build and I will tell you honestly whether I am the right person for it.

FAQ
Can you fix Supabase issues in AI-generated apps like Lovable, Bolt or Cursor?
Yes. I can work on AI-built applications as well as custom projects using React, Next.js and other compatible technologies. The important part is having access to the relevant code and Supabase configuration.
Can you fix Supabase authentication and RLS issues?
Yes. I can troubleshoot signup, login, OAuth, session handling, permissions and Row Level Security policies. I'll review the affected flow and implement the agreed changes.
Can you set up Supabase from scratch?
Yes. I can configure a new Supabase project, authentication, database tables, RLS policies and integrations. The appropriate package depends on the complexity of your setup.
Can you fix database errors, Edge Functions and API integrations?
Yes. I work with PostgreSQL queries, schemas, migrations, Edge Functions, RPC, triggers, Storage, Realtime and API integrations. Please share the issue so I can assess its scope.
What if I don't know what's causing the problem?
That's fine. Share the symptoms, error messages and expected behavior. I'll review the information to estimate the troubleshooting scope. If the cause is unclear or potentially extensive, we can agree on a diagnostic engagement first.
Do you need access to my Supabase project or source code?
It depends on the issue. I may need repository access, relevant logs or scoped Supabase permissions. We can also work through a pull request or deliver code and instructions. Please never send passwords, secret keys or credentials in plain text.
Will you make sure my Supabase backend is secure?
I can review and correct security-related issues within the agreed scope, including RLS policies and data access permissions. This is not a comprehensive security audit or a guarantee that the entire application is vulnerability-free.
What if my issue is too complex for the available packages?
Message me before ordering. For large migrations, extensive backend changes or multiple complex issues, I can review your requirements and prepare a custom offer with clearly defined deliverables.
