    Croatia - Last active: 4 months ago - Tests: 6

    I'm interested in new technologies, computer networks, computer security, operating systems and project management. For the last year I have been working with Microsoft and Oracle databases. Beside their procedural languages I learned how to use XQuery and XPath for querying XML documents in both databases. I have experience with BIND DNS and ISC DHCP and network administration, computer security and with Unix/Linux/Window operating systems.. Before accepting any job I will do a detail interview because that's the best way to find out if I can do a job. I guarantee for my work, before any payment I like to show what I did and answer any question you ask me. If my client isn't satisfied with with my work than I won't ask for any money but I will ask where I did wrong. My moto: satisfied client = happy client
