Fix backend bugs and web app issues
- Views 1
What you get with this Offer
I can help debug and fix one clear backend bug or web app issue in your existing codebase. This could be a server error, broken API route, database/query problem, login/auth issue, frontend-to-backend connection bug, or a small app feature that needs improving.
I'm Lee, a UK-based developer with 6+ years of programming experience. I work with technologies such as JavaScript, Node.js, TypeScript, Python, PHP, FastAPI, Laravel, and more. I'm comfortable jumping into existing projects, reading error logs, tracing app logic, and finding what is actually causing the problem.
What I can help with:
- Backend bugs and server-side errors
- API routes, endpoints, and app logic
- Database or query issues
- Login, authentication, or session bugs
- Frontend-to-backend connection problems
- Small feature improvements
- Error messages and broken user flows
- Existing codebase debugging
What is included:
- Investigation of one clear backend or web app issue
- A clean fix where the issue is within the agreed scope
- Basic testing where your access/setup allows
- A clear explanation of what changed
- Friendly communication throughout
Please message me before ordering so I can check the issue and confirm it fits this offer. If the task involves multiple bugs, a larger feature, database restructuring, or a bigger app rebuild, I can still help but we may need to agree a custom scope first.
What the Freelancer needs to start the work
To get started, please send as much of the following as you can:
- A short description of the backend bug, web app issue, or feature change
- What is currently happening
- What should happen instead
- Any error messages, logs, screenshots, or broken pages
- Steps to reproduce the issue, if you know them
- The technology/framework used, if you know it
- Any affected routes, API endpoints, database queries, or user flows
- Access to the code, repository, staging site, or files needed to investigate
- Any test credentials or setup instructions needed to run/test the project
If you are not sure about some of this, that is completely fine. Just send what you have and I’ll guide you from there.
Please avoid sharing sensitive production secrets unless they are genuinely needed. If credentials, API keys or database access are required, test credentials or temporary access are best where possible.
