    Hi! I'm Breno, I'm a Ruby on Rails and Javascript developer with more than 3 years of Rails full-stack experience( + 2 with Java! ). I run www.fubuia.com.br (Facebook events aggregator for my city), which I code, design and host myself. My strenghts are: - Coding cleanly, I started out with Java and I still care about organized, elegant code. And I learned Rails with developing my own projects in mind, I don't half-ass anything. - English fluent. - GIT fluent. - Proficient in Web Development in general.. I love Web APIs, cool libraries, technologies and tools, front-end stuff, Test-driven-development, etc. - Debugging, I chase bugs in their nightmares. - Typing insanely fast(70-80 WPM ;P) I am bilingual and basically all of my on-line life is written, read and heard in English. My StackOverflow profile/answers may be a good example of this: http://stackoverflow.com/users/586033/breno-salgado This is my timezone: http://www.worldtimebuddy.com/?pl=1&lid=3469058,5&h=3469058 ( Ctrl+C/Ctrl+V the link if it gives error, oDesk may mess the link ) * GIthub: https://github.com/salgadobreno

    David O.

    Data Scientist and IT Pofessional

    United States - Last active: 4 months ago - Tests: 4

    I am a versatile data scientist and IT professional with keen abilities at turning data into insight and for finding the most direct solution to a wide range of technical problems. I create and maintain the systems and protocols necessary to acquire data from the field, extract and transform the data, and develop tools to test hypotheses about that data. Each new extracted feature is a kernel upon which to expand the frontiers of human knowledge; the satisfaction of knowing my work helped a colleague move their research forward is worth every hair-raising moment of uncertainty and technical doubt that may have existed while conducting the analysis. The groups with whom I work tend to create vast streams of data that demand I marshal a broad base of technical expertise (e.g., systems/db admin, data modeling, software engineering, HPC, and web development) as well as maintain the high level of analytical proficiency needed to incorporate the theories and techniques (e.g., EDA, multivariate regression, signal processing, probability and uncertainty modeling, algorithm development, and data visualization) needed to extract meaning from that data. The end result of my efforts mean that I am able to provide new insight into a particular domain of inquiry and create a positive influence on projects that impact society not just locally, but globally. I am part of something much bigger than myself, but am happy that I have been able to do my small part in contributing to the greater good. I truly enjoy what I do and strive to further my knowledge and technical skill set, especially as it pertains to exploring my passions in informatics. My unique blend of scientific curiosity, technical ability, and business acumen make me an ideal data scientist in or outside of the lab.
