If you're here looking for personal projects, besides what's on my resume I particularly enjoyed working on a script for visualizing EVE Online's market, back when I played the game pretty heavily.

(the main script is at https://github.com/gtobkin/evemktvoltreemap/blob/master/src/gen_daily_mkt_vol_json.py)

It scraped market history data from EVE Online's now-deprecated REST API (confusingly called CREST), and then produced a page representing market sectors' volumes with a recursive TreeMap visualization. It also used some parallelization to speed up pulling market data, since the API had fairly limited support for individual bulk requests.
