    Data Scientist

    United States - Last active: 04/04/2014 - Tests: 2

    Over the years I have consistently delivered high quality products by accurately interpreting complicated data needs, understanding complex business processes, recommending approaches and tools, and delivering solutions to improve the operational effectiveness and efficiency of the organizations I have worked for. Specifically, I have implemented solutions that involved geographic information systems, web application development, database design and programming, data visualization and analysis, data warehousing, data mining, business intelligence, and predictive analytics. I have used a variety of tools based on the needs of my customers including the wide range of Microsoft products, SAS, R, Java, Oracle, ArcGIS, JSP, Tableau, among others. My core competency is the ability to understand complex problems and provide workable solutions given a set of resources and tools. I tend not to dictate solutions based on a specific set of tools, but would rather have the problem define which combination of tools, processes, and people would work best. In this case, the old adage applies "Everything looks like a nail when all you have is a hammer." I look forward to working with you.
