    Expert software designer and programmer (Python, Perl, Unix)

    Argentina - Last active: 1 day ago - Tests: 8 - Portfolio: 5

    I am a software designer and programmer and Unix admin. I've been programming for 20 years. More than 10 years of working remotely and I think I'm a very good team player. What motivates me most is to learn something new. My main strengths are my academic background (I studied computer science at the UBA university in Argentina) and that I'm a proactive, independent worker. Whenever I can, I find the answers by myself. Currently I'm interested in non UI, back end jobs. I developed websites (not web design) but that's not what I'm looking for right now. Very good knowledge of: Languages: Python, Perl, C, Unix tools. VCS: Git, svn. DB: Postgresql, Mysql. Non rel DBs: Redis. Web frameworks: Django, Catalyst. Bug tracking systems: Jira, Mantis, Bugzilla. I always worked on Unix and all its flavors, so I got a lot of experience on its usage, networking, administration, operating system internals, etc. Different jobs and curiosity by itself made me learn lots of different languages, APIs, frameworks, like Ruby, PHP, Javascript (esp. JQuery), Twitter and FB APIs, Amazon S3, etc.

    Seeking opportunities in Perl oriented (Catalyst DBIC preferred) application development, shell and perl scripting, and BSD/Linux administration projects - to build sites and setup servers for your business or pleasure.In my mind, LAMP more often reads as LASP - Linux, Apache, (any|no)SQL, Perl - of course, with Catalyst, Template Toolkit and DBIx::Class/KiokuDB in pair with some RCS (git is preferred, but subversion, mercurial and others also possible). And of course, all can be integrated with AJAX libraries such as jQuery, Prototype, MooTools and other to create Web2.0 apptications.Great knowledge of regular expressions (regexp). Have real experience with MySql, Postgres, Oracle, CouchDB, LDAP, also worked with CPanel, Plesk and Ensim.
