    I worked as an artificial intelligence specialist at Pearson for several months after my freshman year of college. I have created novel approaches to a number of natural language processing challenges, and have soundly beat the Stanford NLP project on a number of standard benchmarks. I was scouted by Basis technologies during my sophomore year for work alongside PhDs in the field of Digital Forensics, and Natural Language Processing. I released the first and only open-source sentiment analysis library with near state-of-the-art benchmarks. I have pioneered a number of novel approaches in the fields of predictive analytics and big data analysis, regularly acting as a consultant for the Harvard Innovation Lab. I am currently working with one of the original developers of SolidWorks to create an adaptive gesture recognition platform interfacing with the Leap Motion. I'm fairly new to oDesk, and though I've used it regularly as a project manager, I've not yet signed up as a contractor. Looking for part-time work to discover cool new problems. I am extremely comfortable implementing support vector machines, genetic algorithms, neural nets, latent semantic indexing, pachinko allocation, and a wide variety of other machine learning algorithms, both supervised and unsupervised in Java, Python, C, Ruby, and Javascript.  less
