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

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

I’ve watched the tech landscape evolve over the last decade—from the structured days of Java Server Pages to the current "wild west" of Agentic-driven development. While AI can "vibe" a frontend into existence, I specialize in the architecture that keeps it from collapsing.
My expertise lies in the critical backend infrastructure: the parts that must be fast, secure, and scalable. I thrive on high-pressure environments, such as when I had only three weeks to architect and launch an Ethereum redemption system with minimal prior crypto knowledge, turning it into a major revenue stream.
What I bring to your project:
Forensic Debugging: I don't just "patch" bugs; I use tools like Datadog and Explain Analyzers to map out bottlenecks and resolve root causes—like significantly reducing memory usage by optimizing complex DB joins.
Full-Stack Context: Deep experience in Node.js and React, ensuring backends play perfectly with mobile and web teams.
Sanity in the Age of AI: I bridge the gap between "best practices" and modern speed, ensuring your project isn't just built fast, but built to last.

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.
