I'm a professional Linux (and occasionally BSD) Sysadmin, mostly focussed on web operations, with 16 years experience (and another decade or so fo programming work before that). I've done a lot of development work in perl, and quite a bit of PHP, bash and less recently C.
I'm available for freelance sysadmin support work.
I'm also developing experience in Data Science, and interested in good projects in that direction. I've got some good successful projects under my belt, but also am still rounding out my skill set in various areas.
