As a Wikipedia editor, I’ve written 156 articles, on subjects ranging from GPT-2 and Extremely Online to 1-pentadecanol. Of these, 43 have been featured in the Main Page’s Did You Know section, 19 have passed a detailed peer review process to be listed among the top 0.5% of articles, and one is a Featured Article (Powder House Island, the day's featured article for April 19, 2022).
I've also written a number of articles for the Signpost, of which I'm the editor-in-chief. You can find a list of them at https://signpost.news/Author/JPxG.
You may also find my technical writing and documentation to be interesting. I figured this was normal and not worth bragging about, but after some experience trying to interpret the average software documentation (whether it's for unmaintained decades-old hobby products to costly enterprise software) I've become convinced that skill in the task is somewhat uncommon, and thus noteworthy. The best examples of this can be found on the page of my software projects; in particular, Wegweiser, SVG Spinner, and PressPass feel like the most substantial and complete.
Below is a brief selection of some of the highest-quality Wikipedia articles I've written (all items are clickable links).
