CSGO Betting Website with custpm api

Hello I am looking for someone to do the backend of my website I already have someone designing and doing the frontend of the site. I am looking for someone that can do coding for login functionality, an inventory viewer, selection and trade functions for the bot account, using the steam API, an algorithm to run the probability processing and execute the trades. A function to pull the value of the skins from the csgo analyst API. I can get you in contact with my developer as well so you can understand more of what we need. Let me know and Thank You
