I have started using Linux since 2001 and I work professionally as a Linux administrator since 2004. I have worked for small companies but with big requirements.

United States - Last active: 11/16/2014

Senior Engineer with 10+ years of experience in the IT industry. My experience as a technical lead, senior software engineer, program manager, and architect makes me a perfect candidate for any free lance job you have to throw my way. I currently hold a CISSP and consider myself and expert when it comes to Information Security. Lately I have focused on several different cloud technologies to include integration of legacy software and migration to Amazon Web Services, as well as the Google Application Engine if that is what you are looking to do. Whether it be a small web project built securely, or an enterprise grade software system with cloud integration I have spent years mastering my trade. Lastly, I ran a small business outside of my full time job in which I performed software development of several large and small scale Wordpress sites for Public Affairs clients in the Washington, DC area. I would be happy to answer any questions you may have about my experience or provide you any necessary information that you need.
