    Web Developer

    Switzerland - Last active: 22 hours ago - Tests: 10 - Portfolio: 9

    Over the last five years, building up on my experience of information systems, relational databases, and Object Oriented Programming, I have developed and maintained proprietary web applications combining a PHP or JSP backend, rich media, and responsive frontends using HTML5, CSS3, jQuery, Bootstrap, Backbone, as well as a number of other frameworks. I have also worked frequently with either Java or Adobe Flex, on both the backend and frontend. I am completely fluent with either Drupal, or WordPress, and have developed and marketed premium items for the WordPress platform. I also have experience with more specific environments such as Facebook, Android, or Google App Engine. My primary competence lies in complete end-end management of web development projects, and leveraging the power of distributed systems to offset your costs, while increasing the efficiency of your organization. I want to build the web or mobile application you, or your business has been dreaming of. Because I can.

    Italy - Last active: 12/17/2011 - Tests: 20

    System administrator (Linux / Windows), LAMP developer, Search Engine Optimization specialist. I am working in the IT field by about 10 years as system administrator (Linux and Windows). I'm a good software developer, in particular using LAMP technology. I obtained very good results in the SEO field also. As system administrator I designed and realized the entire network of a small Internet provider; this network has phisical linux servers that hosts some Linux virtual servers, in order to provide firewalling, mail services and web services. The virtual Linux servers gives to this network great flexibility and high availability. During last years I also developed some web applications in LAMP environment (PHP, Mysql, Apache on Linux server). Last year (2008) I worked very hard within a team of engineers for the design and implementation of an application software (web based) that permit the exchange of informations between wireless electronic sensors (designed and produced by the team) and a Linux server. This project gave me a lot of satisfactions.
