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.
Can you optimize API or database performance?
Yes. For projects that require backend optimization, I can investigate slow API requests, database queries, and data-loading issues. This is available depending on the selected package.
Will you guarantee a specific Google PageSpeed or Lighthouse score?
No. Performance depends on factors such as hosting, network conditions, third-party scripts, APIs, and the existing application. I will optimize the areas that can be improved within the project.
What do you need from me to start?
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?
Yes, especially if you're not sure which package you need. Send me your website URL and briefly describe the performance issue, and I can help you choose the appropriate package.
