    I have formidable Linux (RHCA, RHCSE) and Java (SCJP) experience, but I am more interested in Python and Android recently and I gathered some knowledge in many distinct areas (Novell, Oracle, MySQL, PHP, Cisco, etc.). I'm a general IT specialist - non-trivial / multidisciplinar problems gravitate to me, as I like to tinker and dissect problems. Having a bit of OCD (even though I prefer the term "perfectionist") I also enjoy menial tasks like cleaning up databases, commenting code or creating user training manuals. I am looking for side jobs, projects.
