I did a bunch of stuff. Most of it is either ad hoc, useless or cannot be published for one reason or another. Here are a few of my works that are public in this point in time:
Sitemap Generator Crawler
This was one of our earliest worthwhile works as there we no decent crawlers available.
Quebec Expo Science 2016-2017 Project.
Will be open-sourced at this link but only after the project ran it’s course as the software exploits an undisclosed vulnerability to function.
Collectivist is an online chat/forum webapp I had a lot of fun working on.
Leading the overhaul effort on PGGR.org
