Why am I the right man for the job?

I did a complete career from support agent to abuse analyst at 1&1 Internet AG, where I could establish knowledge about many technics that I used in my further jobs. I did support for the whole portfolio of 1&1 products except DSL, which includes linux hosting, linux root servers, common e-mail issues. In the Abuse department we also handled abuse threats for any service.

I am very enthusiastic working in Canada because it is my most favourit country and in the position you offer I can use most of the skills I gathered in my past career. Additional I offer a great amount of experience in handling different abuse cases and automated case management. For me this is a perfect match.
