FAQ
Will you provide a 90+ score on both Mobile and Desktop?
Yes! I specialize in optimizing Next.js for both devices. While Desktop is easier, I focus heavily on Mobile Core Web Vitals to ensure you get a green (90+) score on Google PageSpeed Insights.
Do I need to provide access to my GitHub repository?
Yes, to perform manual code optimization, I will need access to your repository. Alternatively, you can send me a Zip file of the source code. Rest assured, your code is 100% safe with me.
Will the optimization break any features or UI on my site?
No. I perform manual optimization and test every change thoroughly. I focus on image handling, script loading, and CSS without changing your site’s core logic or design.
How long will the optimization take?
For the Basic package, I deliver within 24 hours. More complex full-site optimizations (Standard/Premium) usually take 2-3 days to ensure every page is perfectly tuned.
