    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.

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
