Development of an Interactive Web Game

I am looking for a freelancer to develop a web game. The specific details of the game concept, features, and desired complexity are not yet fully defined. I need a developer who can work on the front-end and potentially the back-end aspects of a web-based game. Please provide information on your experience with web game development and what kind of games you have built previously. I am open to discussing the game concept and requirements in more detail.
