I will fix bugs in node js, react and javascript backend
Yaman T
About this gig
Is your server crashing or API failing?
Code bugs cost you time. I am here to find the issue and fix it fast.
As a backend developer and CS student, I build complete systems using Python and Node.js. I know exactly where to look when code breaks. I write clean fixes and get your app back online.
What I Fix:
- Python script errors and logic bugs
- Node.js and Express.js crashes
- Broken REST APIs and tool integrations
- Database errors (MongoDB, MySQL, Firebase)
- AI integration bugs (Gemini, LangChain)
Why Work With Me? Having built end to end apps handling massive data, I fix the root cause instead of applying a temporary fix. Expect clear communication and zero radio silence.
How It Works:
Please message me before ordering. Describe your bug, and I will recommend the right package so we can get your code running smoothly again!

I build smart backends, integrate AI models, and write Python scripts that save you hours of manual work.
I am a developer with deep hands on experience architecting complex software. I regularly build vector search chatbots using LangChain, custom REST APIs with Node.js and Express.js. I bring this exact engineering precision to your freelance projects. If you need someone to scrape data into a clean spreadsheet, connect your application to an AI model, or build a reliable backend from scratch, you are in the right place.
Message me your project details and let us get started.

FAQ
What do you need from me to get started?
I need a clear description of the bug, the error logs you are seeing, and access to the relevant source code (via GitHub or a zip file). If the bug involves a database like MongoDB, MySQL, or Firebase, I may also need temporary access or dummy data to reproduce the error on my end.
What happens if you cannot fix my bug?
I always ask buyers to message me before ordering. If I look at your code and know I cannot fix it, I will tell you immediately so you do not waste your time. If we start an order and I am unable to resolve the issue, you will get a full refund.
Do you only fix backend bugs?
My primary expertise is backend logic using Node.js and Python. However, I also have experience with frontend technologies like React and Tailwind CSS. If your server issue is directly tied to a frontend component failing to fetch data, I can investigate the full pipeline.
My bug involves an AI chatbot or LLM integration. Can you help?
Yes. I frequently build and debug applications using the Gemini API, LangChain, and RAG systems. If your chatbot is hallucinating, failing to retrieve data, or experiencing routing errors, I can fix the integration.
Can we hop on a quick video call to discuss the issue?
For the $15 Basic package, we handle all communication through Fiverr chat to keep things fast and efficient. For the Standard and Premium packages, we can schedule a quick consultation call through Fiverr's Zoom integration if the bug requires a deeper architectural explanation.
