    Data Scientist:Machine Learning, Statistics, R, Python, Java, VB/Excel

    United States - Last active: 21 days ago - Tests: 5 - Portfolio: 1

    I work with clients on defining, implementing and managing data analysis and data management projects. My expertise lies at the intersection of Statistics, Computer Science and Business acumen. Specific areas of interest to me are education, healthcare, finance, real estate, and energy. Analysis: R (statistics), Python (data munging), Java+Scala (machine learning / big data), VB.NET/Excel (financial modelling) ** Apache Hadoop, Hive, Spark with MLlib (big data ecosystem) ** MongoDB, Neo4j (NoSQL) + MySQL, Monetdb (SQL) ** Gephi (networks/social graph processing) ** Weka (machine learning) Visualization: Tableau (rapid dashboarding), Shiny (R package for interactive statistical dashboards) Environments: Linux, Windows, and Mac (least experience) Productivity: Git (source code control) Web Applications: Play 2 Framework (modern Java/Scala-based, reactive websites) I believe the key qualification to be a Data Science practitioner is an analytic and curious mindset. That said, many hiring decisions seem to hinge on specific skills. Let me know if there's a tool or technology you don't see on my list, and I'll let you know if I've worked with it before.

    Quantitative trading and Machine Deep Learning Specialist

    Spain - Last active: 2 days ago

    As PhD Engineer I am an experienced researcher and currently focus my work on quantitative analysis of financial markets exploring data, asking questions, doing “what if” analysis, questioning existing assumptions. I have ample knowledge of financial markets creating systems and analysing data from big time frames down to order-book data. Tools: Python, R, Matlab, Wolfram Mathematica, C#, F#. Also I have deep knowledge of machine learning, with deep learning networks as my favourite tool.

    Challenge Hunter (Technology + Human Behavior + Data)

    United States - Last active: 02/01/2014

    ***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.
