I have a lot of projects, but my two biggest ones to date are:
A community technology and hosting project that is a cooperation between the Urbana-Champaign Independent Media Center (UCIMC) and Acorn Active Media, Chambana.net hosted a wide variety of services for activist and community groups in Illinois for more than a decade. Currently running but in stasis, its technology is archived on Github. I am the lead system administrator for this project.
Commotion is a free, open-source communication tool that uses wireless devices to create decentralized mesh networks. It is a multi-stakeholder project with the dual purposes of making community network technology easier to use and more secure. I am the co-founder and lead developer on this project.
