Hi there,
First of all, I am new to this website, so my profile and history is almost non existent.
However, I am a game designer myself who worked on multiple projects in life.
But before you even pick me, I will need to know more about your project in order for my to judge if I can do a good job for you. ( We don't want to waste other's time do we? )
I can give you some background, for game design wise, puzzle games are not my strength. Simply because I have very little interest in them.
Other than puzzle games, I have confidence in other areas of game design.
In addition, I will need to know what exactly do you expect from me. Be a overall designer that handles every gameplay/player experience/level design/game balancing OR something more specific.
Lastly, I will be honest here, I have a day job currently, so I will not be able to do a full time. BUT as game design goes, I believe we can work something out of it. ( I believe game design is an on going thing and needs of inspiration rather than counting working hours towards productivity. )
