I will fix bugs, debug errors, or improve your typescript or javascript code
Ildar Sagdejev
About this gig
Your TypeScript or JavaScript code should just work.
If its crashing, slow, or behaving unpredictably, I'll diagnose the root cause and fix it cleanly, reliably, and with clear explanations.
I specialize in solving real-world issues in TS/JS codebases - from small scripts to production systems - with a focus on clarity, stability, and long-term maintainability.
Clients come to me when they need someone who can fix bugs fast, debug stubborn errors, improve performance, or clean up messy code left behind by rushed development or disappearing freelancers.
I deliver clean, reliable fixes with clear explanations so you understand what went wrong and how it was resolved.
What you get:
- Clean, maintainable fixes that wont break later
- Improved logic and performance where needed
- Clear, concise explanations of each fix
- Reliable communication and fast turnaround
Technologies: TypeScript, JavaScript, Node.js, React, Next.js, Express, APIs, async logic, error handling, performance tuning
My guarantee: If I cant fix your issue, you don't pay.
Describe the issue in detail - including screenshots or error messages if possible - and I'll explain the approach I'll use to resolve it.

FAQ
What do you need from me to get started?
A clear description of the issue, steps to reproduce it, and any screenshots or error messages. A repo link or code archive helps once we start the order.
Can you work with React, Node, or Next.js?
Yes. I work with TypeScript/JavaScript across React, Node.js, Next.js, Express, APIs, async logic, and more.
Will you explain what was wrong?
Absolutely. I provide clear, concise explanations so you understand the root cause and how it was resolved.
Can you fix multiple issues in one order?
Yes. The Standard and Premium packages cover multiple issues. For larger scopes, I can create a custom offer.
Do you offer revisions?
Yes. Revisions are included, and if anything isn’t working as expected, I’ll make sure it’s corrected. My goal is for every client to be fully satisfied.
What languages do you work with?
This gig focuses on TypeScript and JavaScript. If you have code in another language, share the details — I’ll let you know right away whether I can help.
Can you work with messy or legacy code?
Yes. I specialize in stabilizing and improving messy, rushed, or abandoned codebases.
Do you need access to my full project?
Not at first. A detailed description and screenshots are enough to start. I’ll request code access only after we agree on the scope.
What if my code is part of a larger application?
That’s totally fine. Just describe the specific issue or area you need fixed. Once we start the order, I’ll review the relevant part of the code and handle it cleanly.
What if the issue is bigger than expected or I need a larger project done?
I’ll review the details and let you know the scope. If it’s larger than a single package, I can prepare a custom offer that fits your project and timeline.
