(Expert) Advice on a website project

Hello Everyone,

Recently, i've been asked to build a portfolio website for a friend of mine. He is a dancer. So we want to really make the website represent itself as a piece of art as close as possible.

Now for some functionalities, i'm pretty much covered when it comes to knowledge. But for others, I've run on a dud. So that's why i'm asking for your expert advice :) !

The website now :

• One page layout, mainly built on bootstrap with some custom css

What I need to build:

• When the user starts on a webpage, a video needs to be played as a banner. - If the user scrolls down or moves away from the video, it pauses -for the portfolio part ( The shows he has been on ) needs to be a timeline. The timeline is scrollable in a vertical way. -The timeline starts from most recent to earliest projects. -A project consists of a description and photos ( possibly a video) -The timeline is placed in the middle of the page and depends on the number of projects ( preferably in a database) -A project starts left from the timeline the next one goes right. This process alternates for each project -The project is shown in a "miniatures". Initially the viewer can see the thumbnail of the project and title of the project (possibly a very small description with it ) -When you click on a project, a little popup window thing should open, showcasing the project in a detailed perspective: -Whole description with all the photos / videos related. -Parallax : it's an enigma to me. What we want : -Ill possibly come back to this later.

-Any advice as to how i need to start building it, what frameworks/libraries/ other things i need to use in order for this to work as optimized as possible ? -Any courses that would really supplement / speed up the process ? -Should i use a database for the projects ? -Any tips on the front end design part? -Like UX, Usability etc. standards that I can implement for a website in the year 2018 and above ?

seeing this overview, i a bit mentally constipated.

Lots and lots of grattitude. Anything helps :D !
