I will fix bugs or improve your javascript or typescript code
Ben El Ansari
About this gig
Is your JavaScript or TypeScript code failing, throwing "undefined" errors, or not working as expected?
I am a software engineer with commercial experience building and debugging production applications using JavaScript, TypeScript, React, and Node.js. I don't just "guess" what is wrongI methodically debug, fix, and improve your existing codebase so it runs reliably.
What I Can Fix & Improve:
- Script Errors: Type errors, undefined variables, and asynchronous (Promise / async-await) crashes.
- API Problems: Broken fetch requests, CORS issues, or JSON parsing failures.
- Frontend & Backend: React component bugs, Node.js server crashes, or DOM manipulation issues.
- Code Quality: Adding strict TypeScript types, refactoring messy JavaScript, and improving performance.
Why Work With Me?
- Fast & Honest Diagnosis: Send me the console error, and I will tell you exactly what the issue is.
- Production Standards: I implement clean fixes that won't break your app again next week.
- Clear Communication: I will explain exactly what was wrong and how I fixed it.
️ Important: Please send me your code and the exact error message before ordering so I can confirm the scope and ensure it fits this gig!

FAQ
How do I send you my code and details?
Once you place an order, you can upload your project files or code directly through the requirements page. You can also share a GitHub repository link or paste code snippets directly into the chat.
What if my bug requires more work than the package covers?
Please message me with your code and a description of the issue before ordering. I will review it and let you know which package fits best, or I can send you a custom offer if it's a larger task.
Do you provide a fix documentation or explain what went wrong?
Yes! For Standard and Premium orders (and available as an option on Basic), I provide a clear summary of what caused the bug and how it was fixed so you can learn from it and prevent it from happening again.
What if the bug still occurs after delivery?
Every package includes revisions. If the specific issue we discussed is not fully resolved, I will work with you to fix it during the revision window.
