FAQ
What do you need to start the optimization?
I need access to your React project files or repository (GitHub/Zip) and, if applicable, hosting access. I will also need a live URL to analyze current performance.
Will you guarantee a 100% Lighthouse score?
No one can guarantee 100 in every case. However, I will significantly improve your performance score and optimize according to best practices for real-world speed improvements.
Do you work with Next.js or only React?
Yes, I also optimize Next.js applications, including SSR, SSG, image optimization, and performance tuning.
Will the design or functionality change?
No. I focus on performance and UX improvements without breaking your design or features. Any structural UX suggestion will be discussed with you first.
Can you optimize large React applications?
Yes. For large apps, I recommend the Premium package which includes deep performance audit, refactoring, and advanced optimization techniques.
How long will the optimization take?
Delivery time depends on your package and project size. Basic fixes take 2–3 days, while full optimization may take up to 7–10 days.
Do you fix bugs as well?
This gig focuses on performance and UX improvements. Minor performance-related bugs can be addressed, but major bug fixing may require a custom offer.
Why is my React website slow?
Common reasons include large bundle size, unoptimized images, unnecessary re-renders, poor API handling, and lack of lazy loading. I will identify and fix these issues.
