    Russia - Last active: 1 day ago - Tests: 6 - Portfolio: 7

    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 expirienced in full-stack development: C programming of RDBMS (SQLite), server-side programming (C/Tcl/shell scripting/etc.), client-side programming (Tcl/Tk), web programming (JavaScript, jQuery, HTML5, css), mobile programming (PhoneGap).

    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.

    Data Scientist and R Expert

    United States - Last active: 2 days ago - Tests: 7 - Portfolio: 4

    I have 7 years of experience in data analysis. I'm the Chief Data Scientist and founder of Cabaceo.com, a data science consulting company in Ann Arbor, Michigan, US. I also teach people how to do data science using the R programming language at www.MasterR.org, where you can receive high quality training materials for free. I used to work as an analytic consultant for FICO, where I built scorecard for Picture People to predict customer response rate to their marketing campaigns, which doubled their ROI. I also built customer segmentations for Canadian Tire Bank, which gave the executive team a holistic understanding of their customers for the first time and resulted in a chapter of a book. More recently, I have built a linear regression model to explain the relationship between interest rate of peer-to-peer loans and borrowers' characteristics using data from LendingClub, a two-level clustering-and-randomForest model to predict human physical activities using smartphone data, a logistic regression optimization based on precision and recall, a R-implementation of the cross-sectional regression and quintile-portfolio construction methods published in the Journal of Economic Literature. I have a masters degree in Biostatistics from the University of Michigan and a bachelor's degree in mathematics from New College of Florida. I'm an avid MOOC taker, constantly learning new techniques and tools in data science and machine learning. I took all the courses in data science, statistics and machine learning from Coursera, Udacity and Edx. I respond all my messages in less than 24 hours.

    Serbia - Last active: 5 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).

    Senior Software Developer

    Canada - Last active: 7 days ago - Tests: 2 - Portfolio: 4

    I have extensive experience developing enterprise-grade network-based web applications and desktop software for clients in government, health care, finance, and academia. I'm the lead developer on several web-based and game engine products, some open-source. I'm strongly familiar with major proprietary and open source development tools and libraries. I'm both an experienced team leader and a fast and reliable solo developer, and as an entrepreneur I understand how to balance high-quality work with the need to ship. I have an academic background with training in both statistics and research methodologies, so I particularly enjoy working on challenging projects that require analysis and creative problem-solving, and which aren't simply clones of existing software. I look forward to working with you!
