FAQ
Can you fix bugs in both React.js and Next.js applications?
Yes! I specialize in debugging both React.js and Next.js. Whether it’s an issue with React or Nextjs, I can resolve if efficiently.
How fast can you fix my React frontend bug?
Most React bug fixes are completed within 24 hours. If the issue is a simple console error or a CSS glitch, I can often deliver the fix in just a few hours. For complex issues, I will provide a clear timeline after reviewing your code.
Can you help with React performance optimization and slow loading?
Yes. If your application is laggy, I can optimize it by fixing infinite rerenders, implementing Memoization, and optimizing your JavaScript bundle size. I focus on improving your Google Core Web Vitals and PageSpeed scores.
I have a Figma design; can you fix my CSS/Tailwind responsiveness bugs?
Yes, I can fix any UI/UX responsive bugs using Tailwind CSS, Material UI, or Bootstrap. I ensure your React components look pixel-perfect and work seamlessly across all mobile and desktop devices.
How do I share my code with you?
You can share your code by adding me to your GitHub repository or sending a ZIP file of the project (excluding node_modules)
