This was my entry for the Downcity.js hackathon in Providence. It's sort of like a location-based Twitter to find trending events and venues. Built with Node.js, Redis, MongoDB and Google Maps. Deployed on Red Hat OpenShift. Find the source on github.
Remoht.usA home automation proof-of-concept using AppEngine, a Raspberry Pi, and an Arduino. Demo running at http://remoht.us. Source is on github.
In 2012, I rebuilt the original 'QiRk' QR-code scanning game as a standalone app where anyone can create a game and print out the QR codes necessary for people to play. It also uses responsive design (Bootstrap) to make it easily usable on any mobile device.
This app was used at the 2012 Rhode Island Maker Faire to encourage participants to explore all of the exhibitors, and let them leave with a catalog of the things they saw! Give it a try at http://qirk.us!

This game has been deployed for two local events, the Providence Wooly Fair and Maker Faire Rhode Island! Unfortunately there's not much to see at the above links since you can't actually play the game without being present at the event for which they were built. The app also won't look terribly good in your browser since it's formatted for mobile screen size. These both run on AppEngine.
