It's all in your <head>
A talk for the Frontend Meetup Freiburg on why the document <head> is where web performance is won or lost.
Hi, I'm Marco Hengstenberg
I'm a front-end web developer who believes the web should work for everyone. I specialise in accessibility, performance, user experience, and content strategy—proving that beautiful websites can be fast, inclusive, and a joy to use.
This website won't track you. I will save the settings from the theme button in your browser. This site also works offline.
