Informational Site with Lottie Animations

I'm looking for a Lottiefiles specialist, to create interactive animations for a website I'm building, to teach real estate courses. Please check out the Duolingo dot com website. Do you see the animation on the left side? I think it's made with Lottiefiles. If you try using Duolingo, you will see these animations are interactive and very cool. I am looking for Lottiefiles specialist, who will work with me to create my courses interesting with the help of Lottiefiles in a similar way they are used in Duolingo. Also, please check attached file, which I wrote before knew that the animation in Duolingo was made with Lottiefiles.
