Interactive JavaScript-based Multiplayer Game Creation

Seeking a seasoned game developer with proficiency in JavaScript to aid in the creation of a simple, live browser card game. The game fundamentally requires:

- Click-based interaction: Affluent understanding of developing interactive game components for players to interact with using mouse clicks.

- Multiplayer functionality: Experience in designing and implementing multiplayer capabilities is crucial. The number of players has yet to be decided, thus, scalability of multiplayer feature is desirable.

Flexibility and adaptability would be key traits as project requirements may evolve over time.
