Great connecting you, Malek.
You are looking for a expert JS developer to build a website based on game. As per your requirement, I can easily build a great Website using HTML, CSS, Typescript, JS, Node.js, Vue.js and Git integrating Discord authentication. I also have hands-on experience with Figma and UI/UX. I can chat with you in a Discord as well.
If you too think, we're a match then let's connect..
Kind wishes.
