You will get Emergency Fix – React + Supabase (Auth, RLS, Policies, Deploy)
Project details
You will get a fast and reliable fix for your React + Supabase application.
I specialize in debugging production issues, broken API calls, failing Supabase rules, authentication errors, and deployment problems.
With years of hands-on experience building full-stack apps with React, Next.js, and Supabase, I work quickly, communicate clearly, and explain exactly what went wrong and how I fixed it.
You’ll receive:
✓ A confirmed reproduction of the bug
✓ A clean and stable fix
✓ Testing and validation
✓ Help deploying the corrected version
✓ A short summary of the root cause
If your app is down, throwing errors, or behaving unpredictably, I can get it back on track — fast, safely, and professionally.

About Marie
Full-Stack Next.js Developer | Supabase, Stripe, AI Integrations
Saint-Jean-sur-Richelieu, Canada - 4:20 pm local time
What I do best:
Full SaaS applications (auth, dashboards, billing, AI features)
E-commerce platforms with Stripe (subscriptions, one-time, Connect, webhooks)
Booking & reservation systems
Database design, RLS, secure API development, scalable architectures
AI chatbots, vector search, and custom assistants
End-to-end delivery: design → backend → frontend → deployment (Vercel)
Clients describe my work with two words: speed and structure.
I start with a solid database schema, build clean components, automate where it matters, and ship results in days rather than weeks.
I’ve delivered complete systems for tourism businesses, e-commerce stores, content creators, startups, and SaaS founders.
About me:
I’m a full-stack developer with real-world product experience, fully remote between Canada and Mexico. I work fast, autonomously, and I can handle everything from architecture to UX, backend, frontend, AI pipelines, security, and Stripe integrations.
Before full-time development, I founded a 5-star sailing company in Mexico (now fully autonomous) and created Set Code & Sail, my technical portfolio and R&D space.
If you need someone who can take an idea and turn it into a real product quickly and professionally, I’d be happy to help.
Let’s build something great.
