I'm a software engineer with the University of Minnesota Libraries, & a strong advocate for FOSS, libraries, and information & technology literacy (including my own). I have deep expertise in PHP & MySQL, and I'm sort of a Rails n00b.
Wherever possible, I proudly take a pedagogical approach to answering. Stack Overflow helped me to broaden my expertise across several areas and I'm thrilled for daily opportunities to help others broaden theirs.
