    Peter Kazazes

    Full service iOS and web developer, startup consulting

    United States - Last active: 1 month ago - Tests: 2

    Since 2009 I have worked with over 50 companies to develop robust, performant, and cost effective software. My primary area of expertise is Objective-C development and web (Java and Node.js, specifically) backends. I pride myself on communication, time efficiency and producing pixel perfect products. I certainly do not only freelance, and the remainder of my resume speaks to that. I continue to freelance to expose myself to new technologies (my role as CTO at Sibyl Vision is primary managerial) and to keep the variety of my coding robust. While I do not offer full time freelance work, the efficacy of my work is such that my part-time work consistently proves as or more affective than my full time freelancing peers. I am based in New York City (UTC-5:00), and am almost always willing to talk business. If you've got a project that is bleeding edge and excites you, I'd love to talk.

    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.
