I will fix, debug or upgrade your supabase and ai web application

About this gig
Did you build 80% of your web app with AI (Lovable, Cursor, Bolt, v0), only to get stuck on a broken database, CORS errors, or Supabase RLS issues?
Take a deep breath. You don't need to rebuild it from scratch. You just need a CTO to step in and finish the job.
Hi, Im Luis Abello, founder of RJ Systems. I specialize in rescuing, refactoring, and scaling high-velocity MVPs. Modern AI is incredible at generating UI code, but it often fails at complex backend logic, relational PostgreSQL schemas, and strict enterprise security. That's where I come in.
WHAT I WILL FIX FOR YOU:
Supabase / PostgreSQL: Repair broken Row-Level Security (RLS) policies, schema migrations, and relational data joins.
Authentication: Fix JWT session errors, OAuth integrations, magic links, and multi-tenant user roles.
API & Webhooks: Debug backend endpoint failures and third-party integrations (Stripe, OpenAI, Resend).
Frontend UI/UX: Resolve React/Next.js state management bugs, hydration errors, and polish broken layouts.
Full App Deployment: Take your local AI prototype to a fully secure, production-ready live URL.
WHY WORK WITH ME?
Standard freelancers patch code; I re-architect systems. I build with strict

One-Line Pitch: High-Velocity MVP Architect & Supabase Expert.
Description:
"Hi, I’m Luis, founder of RJ Systems. I don’t just write code; I launch B2B scalable MVPs. Most founders spend 6 months and $10k waiting for standard agencies. Using modern high-velocity stacks (Supabase, Next-Gen AI Fullstack, custom UI), I turn complex Figma designs or broken AI-generated projects into secure, production-ready web apps in days. Strict modular architecture, Row Level Security (RLS) guaranteed, and clean database logic. Let's build your product this week.

FAQ
I generated my app with Lovable / Cursor. Can you still fix it?
Yes, absolutely. I work with AI-generated full-stack code daily (React, Tailwind, Supabase). I know exactly how AI models structure component trees and where their common database blind spots are.
What access do you need to debug my project?
For database fixes, an invited 'Developer' role in your Supabase project is enough. For the frontend, access to your GitHub repo or your direct AI-builder project link (Lovable/Cursor) works perfectly. You never share master passwords.
My app is 90% broken. Which package should I buy?
Send me a private message first! If your project requires a deep refactor that falls between the Standard ($450) and Premium ($950) tier, I will send you a Custom Offer tailored exactly to your actual scope.
