I have been in the telecommunications industry for over 13 years and have worked as a consultant to major Fortune 500 companies in the past for both business and technology needs. I have a vast knowledge of anything that relates to the internet, both hardware and software realms and have worked on a variety of projects ranging from the simple to large scale transition ones spanning months at a time. I understand a business' need to get projects done right the first time and have always exceeded my clients goals. If they're not happy, I'm not happy. I have a dual bachelors degree from the University of Colorado at Denver in Business Information Technologies and Business Management. My Masters in Business Administration is in International Business and most IT skills I have picked up on my own or through various courses either online or at the local community college. I look forward to working with you and completing any projects you may have, from the quick fix to an entire server farm rebuild. I am also a word class back end programmer familiar with MySQL, Bash, PHP, Perl, and Python. Please, no front end design work, I don't have an eye for creativity (unless it's something simple of course). I look forward to working with you and any projects you may have for me.
