    Project Management and Big Data Guru

    United States - Last active: 04/30/2013 - Tests: 1

    30+ years experience in project management and Big Data. After obtaining my PhD when I turned 24, I started working as a space scientist on high-profile NASA, ESA and IKI missions. Later in my career, my work involved management of large-scale multinationals teams as well as much smaller dedicated teams. I was the software engineer for the multi-billion dollar Infrared Space Observatory and Cluster missions. My background also includes Computer Vision and Artificial Intelligence research. I am deeply familiar with project management and the analysis of Big Data especially time-series. I have also published a number of scientific papers on space science and pattern recognition. On oDesk I have been managing teams of software developers and delivering results since almost it's inception. As of this article I am number two on oDesk for the Test for Independent Contractors and Staffing Managers where I was number one for some years. My core expertise and true passion is project-management especially when dealing with software or Big Data. My private time is spent as the president of the Austin Inventors and Entrepreneurs Association and in producing and hosting two TV talk shows.
