I'm a software engineer living in downtown Brooklyn, NY, with particular interests in operating systems infrastructure, secure computing, and the like. You can probably find me in a coffee shop reading about terminal emulation, writing dynamic libraries to do strange things, or occasionally working on my Debian packages.
On weekdays I develop and maintain software infrastructure for a hedge fund in SoHo, but my blog posts and public projects generally have little to do with my day job or my employer's technical priorities. On Sundays you might be able to find me at St. John-St. Matthew-Emmanuel Lutheran Church in Park Slope, St. Ann and the Holy Trinity Episcopal Church in Brooklyn Heights, or Saint Peter's Church in midtown Manhattan.
I was previously at Moka5, a now-defunct Bay Area startup, where I worked on a Linux-based environment for desktop virtualization. Before that, I was at MIT, where I was a graduate teaching assistant for classes on algorithms, network security, and software security. In January 2014 I co-organized an alumni-run “Caffeinated 6.828”, squeezing a semester-long graduate-level operating systems class into one month.
At MIT I was involved with a handful of student groups, including the Cross Products, a contemporary-Christian a cappella group, and the Student Information Processing Board (SIPB), MIT's student computing organization, where I maintained the scripts.mit.edu shared web hosting platform and the Debathena environment for access to campus computing resources from Debian and Ubuntu.
My preferred email address for most things is email@example.com, and email is my preferred contact method for most things. You're welcome to send me PGP-encrypted mail (key id 5C5245265C413520), though I might be slow to get around to decrypting it. One day, I'd like to work on a better method for secure email. I'm also often reachable on Freenode IRC as
geofft and Twitter as @geofft.
