Original
I have created a web app using AI-assisted coding / vibe coding. The app is already running to some extent, but it is not properly built like a professional SaaS product. Since I am not a programmer, I need an experienced developer to review the entire codebase, clean it up, fix issues, and make it more stable and secure.
This is not a project to build a new app from scratch. The basic version already exists, but because it was vibe-coded, I believe there may be messy code, poor backend structure, frontend-backend connection issues, bugs, security problems, and things that are not production-ready.
I need someone who can actively work with me, understand what the app is supposed to do, inspect the current setup, and then properly fix and improve it.
What I Need Help With
The developer should be able to:
1. Review the full codebase
2. Understand the current frontend and backend setup
3. Check if the frontend and backend are connected properly
4. Fix bugs, broken flows, and backend issues
5. Clean up messy or unnecessary code
6. Improve the project structure
7. Check for security vulnerabilities
8. Secure API keys, backend logic, user data, and database access
9. Make sure users cannot bypass payments, credits, limits, or subscriptions
10. Improve reliability and stability
11. Make the app closer to a production-ready SaaS product
12. Explain the problems and fixes to me in simple language
Ideal Freelancer
I am looking for someone experienced in:
* Full-stack development
* Frontend and backend debugging
* SaaS web apps
* API integrations
* Authentication systems
* Payment/subscription systems
* Database setup and debugging
* Security review
* Code cleanup and refactoring
* Fixing AI-generated or vibe-coded projects
Experience with messy MVPs or AI-coded projects is a big plus.
First Step
Before making major changes, I want the freelancer to first audit the app and tell me:
* What is currently wrong
* What is broken or risky
* What needs to be fixed urgently
* What can be improved later
* Whether the current codebase can be cleaned up or needs partial rebuilding
* Estimated time and cost for the fixes
Deliverables
At the end of the project, I expect:
* A clear audit of the current app
* Cleaned and improved code
* Fixed frontend-backend connection issues
* Fixed bugs and backend problems
* Improved security
* Better project structure
* A more stable working version
* Basic documentation explaining what was changed
* Suggestions for future improvements
Communication
I am a non-technical founder, so I need someone who can explain things clearly and work with me step by step. I do not want generic promises. I need someone honest who can look at the project properly and tell me what is actually wrong.
