FAQ
Can you make my React or Next.js website faster?
Yes. I can identify performance bottlenecks and optimize your website's loading speed, responsiveness, and overall performance.
What performance issues can you fix?
I can work on slow page loading, large JavaScript bundles, unnecessary React re-renders, unoptimized images, API requests, caching, rendering, and other common performance issues.
Can you improve Core Web Vitals?
Yes. I can analyze metrics such as LCP, CLS, and INP and optimize the parts of your application that are affecting them.

Please provide your website URL, describe the performance problems you're experiencing, and provide source-code/repository access if code changes are required.
Should I contact you before ordering?
