I'm mmeier, and I'm here more for the Sins than for the Halo.
I'm the the developer of the PySoaSE program, which checks Sins mods for bugs, errors and things like that, and the SotP Devs have kindly provided me access to their Development repository so I can test PySoaSE on it. In return, I build a system which automatically checks new versions of SotP and reports errors. I like to think that I've been useful at times.
So basically, I'm doing a bit of what's called DevOps for the SotP team.
I greatly enjoy watching modders work, being severely impaired in the area of "producing things which are visually pleasing" myself.
