I participate in developing the backend of our services using node js , Dom , Express , css , html , Bootstrap ,Http requests and routes .
I did many projects that Landing requires to build a multi-section landing page, with a dynamically updating navigational menu based on the amount of content that is added to the page using only js and requires you to create an asynchronous web app that uses Web API and user data to dynamically update the UI .
feel free to contact me if you need my Service , thanks
