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.
