Could you please add space on top of the big title so that you only see that when you land on the page ?

Also, in the sentence:
"Experience seamless integration, swift deployments, and a robust ecosystem designed to supercharge your applications. Elevate your serverless journey with us."
Seems a bit too much, could you please change the "a robust ecosystem designed to supercharge your applications" part pls?

The dark mode is maybe a bit too black and that looks weird.

Other than that it's perfect, really good work!

Changes done, the dark mode will be fixed in the future since it's not the priority right now. (and it's working)
