Help me build a roblox game that is similar to a game like Brawl Stars

I need help from a Roblox Dev for creating a game like Brawl Stars in Roblox I am seeking help in modeling, GUI, global matchmaking, duos, solo modes, animation, and a range of attacks. The attacks will be different depending on the player selecting a Battler (character) and the attacks can be activated by pressing a key on computer and a button on mobile. I will explain the entire project when I receive help.
