    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.
