Long-Term Backend Developer for KarobarAI

Hi,

I am the founder of KarobarAI, an AI-powered SaaS platform for local businesses.

The platform is already built and live, but I am facing frequent bugs and technical issues. I am looking for a reliable backend or full-stack developer who can understand the existing project, fix issues, and manage the technical side of the platform on an ongoing monthly basis.

Responsibilities:

Understand the existing codebase and architecture
Fix existing backend and frontend bugs
Audit and fix the credit system
Fix subscription and plan-related issues
Monitor AI/API usage and identify unnecessary or duplicate API requests
Maintain Gemini and Google API integrations
Manage database issues
Manage AWS/server deployment and infrastructure
Monitor server errors and logs
Fix production issues quickly
Test features properly before deployment
Maintain Google Business Profile integrations
Ensure the platform remains stable for paying customers

Existing project includes:

Frontend and backend
Admin panel
User authentication
Subscription/payment system
Credit system
AI content generation
Gemini/Google API integration
Google Business Profile features
AWS/EC2 infrastructure
Database
Docker deployment
GitHub repository

Initially, I want the developer to:

Audit the complete existing project and codebase
Understand the current architecture
Identify existing bugs and technical risks
Give me a clear technical report
Fix all critical issues
Help with complete documentation
Continue with monthly maintenance and bug fixing

I am looking for a long-term technical person, not someone who only builds a feature and disappears. I need someone who can take responsibility for maintaining and improving the platform while I focus on sales and business growth.

Please apply only if you have experience with:

Node.js / Express.js
SaaS applications
AWS / EC2
Docker
Databases
API integrations
Google APIs
Gemini or AI APIs
Debugging production applications
GitHub
Subscription and credit systems

When applying, please answer:

How many years of backend/full-stack experience do you have?
Have you taken over and managed an existing SaaS project before?
Are you comfortable auditing another developer's existing code?
What is your price for an initial technical audit?
What is your monthly maintenance price?
How quickly can you respond to critical production bugs?
Please share examples of SaaS projects you have worked on.

My goal is to find a reliable long-term developer who can manage the technical maintenance of KarobarAI and help ensure the platform remains stable as we grow.
