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

    United States - Last active: 5 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.

    Ben G.

    United States - Last active: 1 day ago - Portfolio: 1

    I'm currently 23, with over three years experience doing analytics for a large deductible workers compensation provider (whom I'm currently still employed with on a full-time basis). I'm also in school finishing my degree in Math. I'm a tinkerer with a passion for finding creative solutions to data related problems. As much as I love my full time job, I'm on here looking for some extra problems to solve in my spare time (and to make some extra cash while I'm at it). My expertise is in R and Excel/VBA, but I have experience working with a wide variety of languages including Python, SQL, and all things web related. I don't consider myself an expert in programming or statics but I'm good enough in both areas to do some damage. Unfortunately my best work must be kept secret by my employer, but feel free to check out my (somewhat neglected) blog - GormAnalysis.com

    Web application development

    Poland - Last active: 03/14/2011 - Tests: 14 - Portfolio: 13

    In my over 10 years of web development adventure I developed many sites (some of my latest work is in my portfolio) and I grew addicted to coding. About 6 years ago, bored by PHP, I stumbled onto Ruby on Rails which quickly became my favorite tool. I developed 3 large applications by myself and coauthored at least 2 more.I enjoy writing JavaScript code for some time now specializing in jQuery library.For over 4 years I was working as Expert Webdeveloper for largest online auction platform in Central and Eastern Europe, where I share my jQuery expertise among fellow webdevelopers. Later I got promoted to CTO of citeam.pl project (daily deals app). In late 2013 I got another promotion, to IT Manager. I am interested in everything from server administration, Ruby on Rails, node.js backend coding, HTML5, CSS3, JS frontend development to IT leadership focusing on employee engagement.
