    Challenge Hunter (Technology + Human Behavior + Data)

    United States

    ***If you know exactly what needs to be done and don't think there's room for improvement on how it's going to be done, or if you consider the project to be easy or not particularly important, do not contact me or bother reading any further.*** I'm looking for interesting challenges that involve humans, computers, and data to test my understanding. I'm currently most interested in data visualization projects and higher level "systems analysis" projects. But, I'm always interested in problems where someone's well-being is affected. (if necessary, My Rate = Base Rate / (interesting-ness * importance)) Since graduating from MIT Engineering in 2009, I have been working a stream of challenging projects: founding startups, building web applications, marketing technical services, and on and on. Overall, I like to focus on answering the question, "how can we design better Systems to get what we want?" And in thinking about this I've amassed a lot of useful skills and knowledge in both software and just understanding how the world works (and doesn't work.) The more uncertainty you have on what needs to be done, the more help I'll be able to be. I'm very likely the most creative guy you'll ever meet, and what I like to do for fun is think and work on challenging problems.

    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.
