    Full-Stack Developer - Troubleshooter/PHP/Javascript

    United Kingdom - Last active: 3 days ago - Tests: 5

    With a strong technical background in both Windows and Linux server administration, I consider myself to be a highly skilled internet & technology all rounder. Combining both experience and knowledge I can quickly identify and assess customer/client needs and find solutions to suit their requirements. I have been working successfully as an independent remote contractor for over 7 years and have built up particular strengths in MS server products especially SQL Server & IIS - with strong coding skill in javascript/jquery, PHP and experience in many other broader web technologies. I pride myself on being a fast learner and just enjoy making things work. I have been able to maintain long term relationships with my clients and am eager to continue to do so having recently completed a long term contract at another oDesk employer. Having worked in corporate IT for 7 years in a very high service availability environment, I know how to work under pressure whilst adhering to process. My key personal strengths include a keen attention to detail, excellent troubleshooting skills and an easy-going demeanour that helps me build strong working relationships quickly.

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

    Argentina - Last active: 3 days 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.
