    Clinical Researcher with Published Experience

    United States - Last active: 5 months ago - Tests: 2

    My background and training is in clinical psychology, with major emphases in clinical science and research and associated writing. I've over 7 years' experience in clinical research, and completed my Master's degree (PhD is in the works) with a clinical research internship (at which I excelled & turned into a paid position) at Mayo Clinic. I'm a published scientific article writer, have given talks and presented work at international scientific conferences, and have been listed on colleagues' work that's been presented at many more. These experiences have required that I learn and/or teach myself all of the following: - Advanced OS customization skills, such as automation and custom script/utility/software development - Database administration and security - Technical and scientific writing - IT support and troubleshooting - Statistical analyses (advanced) - Project management and recruitment

    Carlos Rivero

    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.

    Director

    United Kingdom - Last active: 06/06/2014

    As a specialist consultant with a background in major, multinational, data-driven science projects, I draws on skills that have been applied and demonstrated in some of the most demanding data analysis settings imaginable, specifically cutting edge space research. I offer services in the following areas: * Policy and Strategy I help corporate and public sector organizations fomulate policies and strategies to foster the use of data and data analysis to achieve organizational goals. With my public science background I have a keen interest in the policies and strategies needed to ensure open data is an integral part of the way the public sector engages with business and communities. * Data Analysis and Numerical Modelling As a data analyst I am experienced at working with small and "big-data" volumes of data. I undertake novel investigations combining data, simulations and statistical methods (such as Bayesian inference and causal modelling) to create models from which quantifiable decisions can be made. I also create analysis pipelines to routinely turn base data into higher level products, such as visualizations, and make it more useful and accessible to end users. * Software Development With over ten years experience writing software in Perl, Java and C++ to crunch numbers in HPC environments, I have the skills needed to turn analysis and models into deliverable software modules; either as stand alone tools or for integration into client systems. What I do goes beyond mere number crunching. Having written end-to-end processing pipelines I have included stages for manual user interaction and input (such as for quality control purposes) and have written the tools needed to archive results and provide user access through different interfaces.

    Analyst, QA-Engineer, Technical Writer, Content Manager, Proofreader

    Russia - Last active: 6 days ago - Tests: 12

    I am a business/system analyst, QA-engineer, and technical writer skilled in the design of software requirement specifications (SRS), test cases, user manuals, and help systems. My total experience of a remote work at software development teams exceeds 9 years. Also, I have a many-years experience of the content management, including translations, proofreading, editing, and annotating (for reviewed scientific journals) as well as data mining, rewriting, and copyrighting (for public web-projects). In my opinion, my main strengths are my mathematical background (I have a postdoc degree in Math and I use that as a basis for all projects required the data analysis) and my comprehensive expertise in VBA macros for Excel and in editors of the TeX-group (TeX/LateX/AMSTeX).

    Philippines - Last active: 21 days ago

    I've used PHP and Drupal CMS on previous web projects. GNU/Linux is my preferred development, testing and production environment. My interest on embedded system (C and embedded Linux) brought me to a project which created a mobile ticketing system for metro buses. I've been an enthusiast of data analysis since my days in the University - working on a large scale eigenvalue problem. I am interested on projects with interesting data sets. I've been involved on various advocacy issues (cybercrime law, free and open source, automated election, mass surveillance, etc) related to use of ICT. I am a volunteer of Computer Professionals' Union which "advances ICT for the People" in the country.
