FAQ
What do you need to start?
I need your website link or source code (GitHub/zip). If it’s not deployed, I can still work with the codebase.
Will my design or UI change?
No. I only optimize performance. Your design remains unchanged unless you request UI improvements.
Can you guarantee Lighthouse 90+?
I aim for the best possible score, but results depend on project size, structure, and third-party dependencies.
Will my website go offline during work?
No. I work safely on a separate setup so your live website is not affected.
Do you also fix bugs?
Only performance-related issues are included. For general bug fixing, please check my other gig.
