    United States - Last active: 10/24/2012

    An internally motivated NLP engineer with a passion for computational linguistics and an inability to relax. Just as comfortable fifteen pages into a research paper as committing code to a weekly build. Experience in syntax/semantics, text analysis, named entity recognition, sentiment analysis, and parsing social media makes for a silver bullet on any problem with unstructured text. This stuff keeps me up at night.

    iOS, Social Algorithmic Backends, just about everyting else

    United States - Last active: 03/15/2014 - Tests: 2 - Portfolio: 6

    In 2009, I created a whimsical and, in retrospect, ridiculously unpolished directory of Atlantic shark species for iPhones and iPads. It was written in HTML and ran natively with the help of the then-omnipotent Phonegap wrapper. If you look at it now, it looks like many of the other rushed-out-the-door apps of its time. "Shark Mate!" was a UI and programatic disaster, but it was my disaster. The few dozen downloads a day I was getting in 2009 kickstarted a drive within me to develop things. A drive that, in time, will surely have a proper name due to its pervasiveness in my adolescent developer peers. Five years later I'm playing in a different league. In the intervening years, I have worked with some amazing companies, lied about my age more than a few times, tackled some pretty hefty big data, and learned a hell of a lot. My biggest claim to fame thus far has been predicting the 2012 election to 0.75% of the popular vote using my own social media-based sentiment analysis algorithm. I'm no Nate Silver, but if you run in to him let him know that I'll show him mine if he shows me his. Today I oversee my company, Sibyl Vision, and have yet to drop the freelance gig.
