I am a machine learning enthusiast, check out my text classification API here uclassify.com. I am pretty happy with the implementation of my own translation algorithm.
If you are into number sequences, my hobby project sequencedb.net might interest you, it's a database of procedurally generated integer and decimal sequences.
Games are also fun to program you can see some of my creations at playchilla.com. I've published the source code for a b-spline noise thingy. Also pretty happy with an unreleased implementation of Advancing Front/Marching triangle, video here. Professionally I've worked on DICE (2006-2008), King (2009-2011) and Mojang (2012-currently).
