    Information Technology and Security Expert

    Romania - Last active: 4 months ago - Tests: 8

    I enjoy investigating a multitude of subjects, for example when I was 14 I started to learn PHP, three weeks after I was programming an internal chat system for a casino in Holland. Afterwards, small web-related projects followed; when I was 16-17 I was hired as a company administrator in the fields of IT Security, Computers and Network administration/installation, CCTV surveillance, PBX administration and Access Control. At 18, I've started to research the field of reverse software engineering and subsequently developed web-crawlers/spiders as well as playing around with various programming languages. Soon after, I have found interest in the field of Ethical Hacking and developed applications regarding protocols such as POP3, SMTP, FTP and I have also conducted research on how the aforementioned protocols can be correlated in order to subdue RDP-enabled servers. To cut the story short, I have a diverse interest which spans a multitude of IT related fields.

    Javascript/PHP Web Developer

    Russia - Last active: 4 months ago - Tests: 4 - Portfolio: 3

    Last six years I performed different tasks in the field of web development, such as programming web-site backend on PHP and Perl languages, drawing templates and making page layouts, adding interactive elements, input handlers and AJAX-driven features using JavaScript (jQuery, Angular etc). Also I have the server administration skills, so I can setup and manage UNIX-servers, system software and solve problems. I'm most interested in web-service development projects, or working part time in a team. To prove my skills and get more information I always welcome small test projects before starting main work.
