About this gig
Your React, Angular, or TypeScript app is broken. I'll fix it and tell you exactly why.
10+ years building and debugging frontend apps across React, Next.js, Angular, AngularJS, TypeScript, and JavaScript. 74 projects at 4.9 stars. Clients keep coming back because fixes are permanent and I explain everyone.
What I fix:
- React & Next.js: hooks errors, state bugs, SSR issues, rendering problems
- Angular (217) & AngularJS: routing, lifecycle, module conflicts, service injection
- TypeScript: type errors, compilation failures, interface mismatches
- JavaScript: async/await bugs, promise chains, runtime errors, scope issues
- API integration: CORS, auth token errors, request handling bugs
- HTML/CSS: broken layouts, responsive failures, cross-browser issues
- Form validation: broken validators, async validation, submission errors
My process:
- You share repo/code + console errors + steps to reproduce
- I find the root cause, confirm scope, then fix it cleanly
- You get a written summary of what broke, what I changed, and how to prevent it
Message me before ordering if you're unsure I'll review your issue first.

FAQ
What types of issues do you fix?
JavaScript errors, Angular/AngularJS bugs, React/ReactJS issues, HTML/CSS layout problems, API integration errors, and form validation issues.
Do you work on existing projects or only new code?
Primarily existing projects. I dive into your current codebase, identify the root cause, and fix it without breaking other parts of the app. I can also add small features or improvements alongside bug fixes.
Do you fix backend or server issues too?
I handle API integration and frontend backend connection issues. Full backend fixes depend on the stack to be discussed first.
Will you explain what caused the bug?
Yes, always. Every delivery includes a written explanation of what caused the issue and what I changed. For the video walkthrough extra, I also record a short screen capture walking through the fix. Understanding the cause prevents the same bug from coming back.
What do you need before starting?
Source code or repo access, a clear description of the issue, screenshots/errors from console, and steps to reproduce the problem.
What types of bugs and errors do you fix?
JavaScript runtime errors, React and Next.js bugs, Angular (2–17) and AngularJS issues, TypeScript compilation errors, HTML/CSS layout problems, API integration errors, CORS issues, authentication bugs, and form validation failures.
Which package should I order?
Basic is for a single specific bug you can clearly describe. Standard covers up to 3 bugs or a broader problem across multiple components. Premium is for complex projects needing deep debugging, refactoring, or API fixes. Not sure? Message me and I'll recommend the right one before you order.
What do you need from me to get started?
Your source code or repo link, a description of the issue, any console error messages or screenshots, and the steps to reproduce the problem. The more detail you provide, the faster I can fix it.
