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

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

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.
