Dear Hiring Manger,

I am passionate about Information Technology and seeking a position that can leverage my skills and talents that I have developed over the course of twenty plus years working in a 24x7x365 healthcare environment. In the last few years at Ascension my primary focus has been on very large compute platforms; however, prior to that I have directed all aspects of information technology from software development, networking, email and collaboration services, to systems management. In addition, I have served as a corporate designee in legal proceeding surrounding a large outsourcing agreement, large vendor executive relationship management and have extensive strategic planning experience with information technologies and an emphasis on cloud migrations. I also bring a strong security focus on the highly confidential nature of healthcare data with HIPAA regulations which has prepared me to translate that protection of data from healthcare to other industries that require a high level of data protection. In addition, I am currently pursuing my CCSP (Certified Cloud and Security Professional) Certification to further my preparation for moving business functions into the cloud in a secure and protected manner with the appropriate business continuity and disaster preparedness options to the cloud providers. I have recently passed the CCSP exam and awaiting my certificate from the ISC2.
