Data Not Saving to Database in My AI App
You fill out a form or perform an action in your app, it looks like it works, but when you refresh the page the data is gone. The database isn't saving anything, or data disappears after a page reload.
Error Messages You Might See
new row violates row-level security policy
relation does not exist
column does not exist
42501: permission denied
23505: duplicate key value violates unique constraint
Common Causes
- Database connection is failing silently
- Row Level Security (RLS) policies are blocking inserts/updates
- The app is saving to local state but not making the API call to the database
- Database table structure doesn't match what the app is trying to save
- Missing or wrong database URL in production environment variables
How to Fix It
- Open browser Network tab (F12 > Network) and watch for API calls when you submit data — check for errors
- If using Supabase, go to the SQL editor and check if the table exists and has the right columns
- Check RLS policies — they're the #1 cause of data not saving in Supabase apps
- Verify your database connection string in environment variables
- Check the server/API logs for database errors

Currently focused on AI integrations, automation tools, and TypeScript-first architectures.
Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
Data saves but disappears after refresh. What's happening?
The app is probably saving to local state (React state, for example) but not actually calling the database API. Check the Network tab for API calls when you submit.
I see a 'row-level security' error. What does that mean?
RLS is a Supabase feature that controls who can read/write data. The AI probably created tables without proper RLS policies. You need to add policies that allow your users to insert and read their own data.
