Christopher Ramsburg
Summary
I thrive in high-pressure and fast-paced situations, accepting only positive results by applying my ambition and critical thinking abilities. Further, I possess expertise in high stress scenarios and acumen for maximizing performance and inspiring colleagues. These skills and more were developed over the course of nearly twelve years of direct service to the President of the United States and staff. In this short but fulfilling mission I was tasked with managing three geographically separated data centers that encompassed five domains and 3,800 client systems, communicating with vendors and stakeholders within and outside of my own job function or external to the organization, and leading large or complex projects that involve technically challenging requirements, involving delegation of work and review of work products. I have skillfully balanced organizational objectives and productive relationships, strategizing and recommending a way in which to achieve and maintain a competitive business edge. My planning and problem solving talents have supported my professional and academic growth. I currently work as the Director of the Network Management Center for the Defense Information Systems Agency, where I have been able to further strengthen my technical and leadership abilities.
