I have experience writing safe, robust automation utilities for my own purposes, and am fully capable of writing even safe shell scripts. If need be, I am perfectly capable of monkey-patching web applications written in just about any language, and have successfully mended errors in systems I did not understand until I read the pertinent error message -- I am well-regarded among my peers for learning on demand.
If you need a server fully, securely configured, from the operating system up, I am more than capable. If you need a program to batch-convert file formats, I can provide. Any medium-sized piece of server or command-line software, I am likely able to produce.
Projects with a concrete deliverable are ideal; this could be anything from a piece of software to do a particular task, to a fix or patch to an existing piece of software; from an up-and-running installation to a set of updates to an operating system.
I look forward to hearing from you.
