Get some pointers from a friend who is a native speaker. I still do this today even though I'm (IMO) well versed in the language.

For instance:

welcome on -> welcome to

web-side -> webside? (unsure)

working as front-end -> working as a front-end

i want u -> unsure what that means

besides that, any specific front-end js platforms? (maybe put angular before jquery in your cv?)

on mobile, the about me page has the linkedin/github icons on top of the "contacts" page. lastly: besides those minor things, your website is PRETTY COOL
