I am a game designer,
I think my most relevant qualifications would be that I worked on Sleeping Dogs as a mission designer, and have been modding TES since Morrowind, and even hacked a bit of Daggerfall. I mostly end up downloading mods from others and changing them to suit myself. Although I have ended up doing some player homes, towns, and overall world geometry/ dialog/ quest mods for myself just to change the game to my liking as I play the various Bethesda games.
I am currently involved in academic research into modding and modder communities in terms of participatory production as gameplay using an autoethnographic approach. So this project would be great for looking at mod community contexts more formally. Have also been teaching game design and level design for many years. There is a high chance that some people on this project are my former students, and it would be great to reconnect with them randomly in this context.
I think I would be most useful to edit/ test world spaces and quests. But any sort of gameplay/ UX/ balancing/ engagement aspects; any game design would be something I would be comfortable handling. I would offer to handle some project management but at the current time I don't feel like I could offer enough hours per week to be effective in that capacity. I feel like I have a lot of experience to offer, but would like to start out small, just tell me what needs done, and I'll see to it.

PM sent for coding.
