[Gsap observer and and scroll tirgger expert required urgent $100/hr]

If you are an expert, hit me a message right now, please contact me right now I have a few hours of work today, it's urgent.  If you have experience in the observer, that would be great otherwise, the scroll trigger will work, but I need premium quality of smoothness and finish in animation. Html is already ready you only have to apply the gsap code for animation. I need an expert who can apply the animation right away, not a beginner who needs days to create animations. 

 

[Structure of one pager website is ready in webflow, need a freelancer to apply only the scroll trigger animations.]

We are looking for a gap animations expert on regular project basis work. Please message me to get details. 

[I want to improve the animation that is already done in codepen and some scroll snap type function add to it.]

Here is the example animation I want to achieve https://dribbble.com/shots/15292175-Product-Carousel-Experience

1. I want to make the animation  smooth like the example of dribble I shared above
2. it's not scrolling smooth on mouse wheel, like I think  if mouse is scrolled many times in one go it should only trigger one animation and don't go directly to next slides. 
here is the real code that you can modify

Please help me.
