AI Generated Nextjs FastAPI App Cleanup and Fix

Got an app built with Claude Code, Cursor, v0, Lovable or ChatGPT that is buggy, untyped, insecure or not production ready?

I turn messy AI-generated Next.js 14 + FastAPI code into clean, secure, scalable and maintainable applications.

What you get:

  • Full code review and bug fixing
  • Clean architecture and strong structure
  • JWT Auth + RBAC
  • Rate limiting
  • PostgreSQL + SQLModel
  • Documented API contracts
  • 100% typed code (TypeScript strict + mypy strict)
  • Alembic migrations
  • NextAuth, Zustand, TanStack Query
  • Tailwind + modern UI
  • PWA ready frontend
  • M-Pesa and fintech ready (Kenya experience)

Backend: FastAPI SQLModel PostgreSQL JWT RBAC Rate Limiting Alembic

Frontend: Next.js 14 App Router TypeScript strict NextAuth Zustand TanStack Query

Why choose this service:

  • Production-focused workflow (not just prompts)
  • Clean code that is easy to maintain and scale
  • Real experience with fintech and marketplace apps

Message me before ordering with your repo or issues. I will confirm the best package for you.

Clean code. Strong architecture. Reliable apps that are easy to maintain.

I’m a Python and full-stack developer working with FastAPI, PostgreSQL, Next.js, and TypeScript. I build web applications, APIs, web scrapers, and automated data pipelines. I also review, fix, refactor, and extend AI-generated apps built with tools like Claude Code and Cursor. My development work includes JWT authentication, role-based access control, rate limiting, database migrations, typed APIs, and modern Next.js applications. Whether you need structured web data or help improving an existing codebase, I focus on practical, reliable solutions.
