About this gig
Need help with a TypeScript bug that is slowing down or blocking your project?
I can investigate, diagnose, and fix TypeScript issues in your existing application or codebase.
I can help with:
- TypeScript errors and type-related issues
- Runtime bugs and unexpected behavior
- Async/await and Promise-related problems
- React and Node.js TypeScript issues
- API integration bugs
- Build and configuration problems
- Performance-related issues
- Failing tests and regressions
I have over 15 years of professional web development experience, including extensive work with JavaScript, TypeScript, React, Node.js, and production codebases.
Please contact me before ordering if the issue is complex or if you are unsure which package is the best fit.
The Basic package covers one small, clearly defined bug. Larger issues, multiple bugs, architectural changes, new features, or extensive refactoring may require a Standard/Premium package or a custom offer.
To get started, please provide reproduction steps, error messages, relevant source code or repository access, and any other details that may help reproduce the issue.

FAQ
Should I contact you before placing an order?
Yes. I recommend contacting me before ordering, especially if the issue is complex or you are unsure which package to choose. Send me a short description of the problem, and I will help you select the most suitable option.
What does the Basic package include?
The Basic package includes investigation and fixing of one small, clearly defined TypeScript bug. If the problem requires extensive debugging, refactoring, architectural changes, or involves multiple issues, a larger package or custom offer may be needed.
What information do you need to get started?
Please provide a clear description of the issue, steps to reproduce it, error messages or logs, expected and actual behavior, and access to the relevant source code or repository. Screenshots, recordings, or failing test cases can also be helpful.
Can you work with React or Node.js TypeScript projects?
Yes. I can help with TypeScript issues in both frontend and backend projects, including React, Node.js, API integrations, build errors, and runtime bugs.
What happens if the issue is larger than expected?
I will explain what I found before doing any work beyond the agreed scope. If additional work is required, we can agree on a larger package or a custom offer before continuing.
