I do mostly tweaks and "beneath-the-surface" maintenance of articles, with the occasional content creation thrown in for good measure. I also devote some of my energy to cleaning up promotional, heavily biased articles full of puffery. If you are interested in the details, you can peruse my edits
here.
If you are confused by or object to something I have done, you can leave a message on
my talk page. I'll be happy to talk things out and clarify them.
