Design a Web Page

Hello, I am looking for an experienced web developer in front / back end to create a betting page working with the Steam API (connection, inventory skins), a steam robot to manage trades, and a custom API to create events Details: You create a match by selecting the region (EU, NA, AU), the mode (1vs1, 2vs2, 3vs3, 4vs4, 5vs5), you choose the card and how much you want to bet (for each team), after that, the creator of the game has 2 links (these links can be re-generated), one to invite the teammates if the match is not a 1 to 1 and one to invite the opponents (the first opponent who joins will be the owner of the team (transferable in one click)), when everyone is connected on the match, everyone can send his skins to reach the bet of his team, when all the teams reach him the match is ready to be played, the creator must click on'PLAY ', he creates a new line on the DB with all the Steam Ids, the unique ID of the match etc ... At the end of the match, I call the custom API to send the results of the match, the bot takes a% of the skins and sends the rest to the owner of the winning team. The owners of the match also have the opportunity to expel players from the lobby (the creator of the game, everyone, the owner of the second team, only the members of his team). requirements Professional experience (Portfolio?). Flexible work schedule Active (IMPORTANT) Experience PHP HTML CSS MySQL JavaScript NodeJS Thanks
