    I have a Master's degree in radiophysics and electronics. In addition to fundamental mathematics and physics knowledge I specialized in computer simulation and computer vision technics. My experience ranges from research to applications. I prefer simple solutions and reliable technologies. I make compact and fast applications having a vast background in producing firmware for embedded devices with relatively small RAM, slow CPU, and very long uptime. Cross-platform programming is not hard, it is the only way :) In addition, I am experienced in full-stack development: * client-side programming (python, R, Tcl/Tk), * server-side programming (python, R, C, Tcl/Tk, shell scripting, etc.), * database programming (PostgreSQL, SQLite, OpenLink Virtuoso), * C programming of RDBMS (SQLite), * web programming (JavaScript, jQuery, HTML5), * mobile programming (java, PhoneGap), * and some other.

    Data Scientist

    Spain - Last active: 1 day ago - Tests: 16 - Portfolio: 5

    Do you have some question that requires a statistical or machine learning answer? No problem. As a data scientist with 15 years of experience, I have the technical knowledge and the communication skills needed to solve your problem and, most important, give an answer that you can apply to your field of interest. What I offer to you is a full data analysis/machine learning stack, including: - Getting and organizing your data. - Selecting the most relevant statistical or machine learning technique for your case. - Applying the technique to your data. - Writing a report that explains every step taken and makes a interpretation of the results. All written with enough technical detail, but that doesn't require a depth statistical knowledge to follow. - Assistance in applying the results to your specific field. I can do all this using any or several of the following: R, MATLAB, Python, MySQL. Everybody can apply an out of the shell statistical algorithm to some benchmark data. But I'm an expert in the tricks needed to apply those algorithms to real data.

    Serbia - Last active: 7 days ago - Tests: 2

    Learn through data analysis, would be the tag line for me. I am a data scientist with business intelligence and text analysis background. I am also a JAVA/php/javascript developer, like databases, have a PhD (if important). Strong incentive to build systems that analyse and learn from data. I've done this for the last 8 years in academia and industry, and will try to do it for a long time (still only 30).

    Belarus - Last active: 7 days ago - Tests: 3

    Over past 4 years I've been working with the big american companies. They involved me into dozens of projects connected to the data analysis, web analytics and reporting. I am using one of the most exciting tools for providing data insights called Tableau. Since data analysis requires knowledge of any query language MySQL is another "tool" I am expert in. As web analyst I have a lot of experience in Google analytics, DoubleClick Floodlight, Google Tag Manager, SiteCatalyst, etc. I helped my clients with Google Analytics E-commerce implementation and set up. I am always in touch with any Google's updates and recommend to my clients best in class solutions existing on the market. I am very open for any new projects and ready to get started.

    Sr. Project Planning, Scheduling and Data Analyst

    United States - Last active: 20 days ago - Tests: 7 - Portfolio: 3

    Hello! Do you have a project you NEED to keep on schedule and deliver on time? For every milestone you miss you are in danger of missing your delivery date. Schedule slips mean you reduce your profit and your customer loses confidence you can deliver when you said you would. What you need is a project plan and schedule that will help you keep track of your project. Your schedule needs start of project, durations for each task, and a good logical network of predecessors and successors. Once you have that you need to baseline your project so at the end you can analyze where the bottleneck might have occurred. Let me help you build a realistic schedule so you can meet delivery on schedule which will help you deliver on budget. I have helped major aerospace companies achieve their goals on delivery saving them lots of $$$. I've also started helping out small companies so they can grow and profit as they implement better planning for their projects and products. Remember, you need to keep track of your projects and your production/services to optimize your business. You need my help whether your business is virtual or you have a physical location. Let me know if you have any questions. Regards, Minerva
