    Full-Stack Developer - Troubleshooter/PHP/Javascript

    United Kingdom - Tests: 5 - Portfolio: 1

    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.
