I will fix your broken nextjs saas backend, database and ai code
Nick Saperov
About this gig
Did you build your SaaS MVP using Cursor, Claude, v0, or ChatGPT? Does it look beautiful on the frontend, but the backend is crashing, the database is a mess, and the AI keeps saying "I apologize, let me fix that" in an endless loop?
You have hit the AI Code Wall. AI is incredible at generating UI components, but it fails miserably at secure database schemas, complex API routing, and Serverless architecture.
I am Nick, a Solutions Architect specializing in Next.js and Serverless ecosystems. I don't just "write code" I rescue broken, AI-generated spaghetti code and refactor it into production-ready infrastructure.
How I rescue your MVP:
- The Triage: I audit your Next.js codebase to find exactly why your API is failing or your database is overwriting data.
- The Hotfix: I rewrite the critical business logic, fix your auth loops, and secure your backend.
- The Rebuild: I restructure your app using strict Zero-Build Serverless Edge architecture so you can actually launch.
Stop wasting your runway trying to prompt your way out of a broken database. Send me your GitHub repo, and let's get your SaaS ready for production.

FAQ
Will you deploy the fixed app for me?
Yes, I can set up your Vercel or cloud deployment environment as an Extra Service to ensure it runs perfectly in production.
What tech stack do you rescue?
My core expertise is React, Next.js (App & Pages router), Node.js, and NoSQL/SQL databases (Firebase, Supabase).
Do we need a live Zoom call?
No. You send me your GitHub repository and a list of what is broken. I will analyze the code and send you a Loom video explaining the technical flaws and how I will fix them.
Can you work with code entirely written by Cursor or Claude?
Absolutely. I understand exactly how LLMs structure code (and where they make critical mistakes in state management and backend security). I will untangle it.
