I'm Jeff. I started Folded ages ago as a place to publish a variety of personal projects. You can find many of them at the main page. Some other projects (like Grumble) have since closed up shop, or weren't ever public.
Some folks call me "Fish"; it was my pseudonym for several projects. Still other folks know me as the Fish from Folded – the "Folded Fish".
If you're looking for my more professional side, you can find that over at yaus.com.
