In particular, I'm very competent at 1. data scraping 2. data wrangling 3. descriptive & exploratory analysis 4. data visualization 5. inferential & predictive analysis 6. pattern recognition and clustering 7. supervised & unsupervised machine learning algorithms 8. building analytic web apps 9. the R programming language Some of my recent for-fun projects include a couple of analytic web apps and a book on how to do data analysis using R. They are listed under the portfolio section below. Make sure you check them out. I also love to teach people how to use R to do data analysis, and I do that through MasterR.org, an online community where you can receive high quality training materials for FREE. I used to work for FICO, where I built scorecards for the Picture People to predict customer response rates to their marketing campaigns. My scorecards doubled their ROI. I also built customer segmentations for Canadian Tire Bank. It gave the executive team a holistic view of their customers for the first time. I have a master's degree in Biostatistics from the University of Michigan and a bachelor's degree in mathematics from the New College of Florida.

    CTO - Skilled IT Business Consultant and Project Manager

    Estonia - Last active: 12/17/2014 - Tests: 1 - Portfolio: 3

    I'm a CTO at heart. With 5 year experience in IT development & startup bootstrapping, my core strength lies in a rare business execution + IT dev experience & competency. I have hands on experience in managing small agile dev teams and even programming (C, Java, Play, PHP, SOLR, AWS, SQL, noSQL, ...), bringing new IT products to life and maximising the investment potential of the technology. Why would you hire me? I'm the perfect fit for the entrepreneur / CEO who requires trusted high-level technical consultancy (cloud services, big data, machine learning, search servers, distributed application, mobile servers, ...) and needs someone to manage the development team (or even hire and get them to work in no time). Business plans I personally wrote and detailed experience in managing dev teams available upon request.

    Quant Finance, Trading Strategies, Algorithms, C#, Python, MATLAB

    United States - Last active: 12 days ago - Tests: 2

    If you want to create a trading system, run a statistical analysis, develop a pricing model, build a financial GUI, or find a pattern in a sea of data, I may be the guy to help. I work primarily in MATLAB, C#, and Python. On the finance side, I'm a CAIA Charterholder, with an Economics degree and experience at McKinsey & Company. On the technical side, I hold degrees (with honors) in Engineering, and worked at a number of California tech companies through the 1990's and early 2000's. Since 2008 I've focused my work in the field of computational finance. Recent clients have included: a Swiss proprietary trading desk (Energy Futures), a Canadian hedge fund (Currencies), a US asset management firm (Equities & Bonds), a US portfolio consulting firm, a US aircraft manufacturing operation, and several others. For those clients I have developed, backtested, and deployed alpha-seeking trading strategies, automated execution algorithms, portfolio optimization models, user-friendly GUI tools. Techniques have included machine learning algorithms, classifiers, feature detectors, digital filters, matrix-based models, and concepts borrowed from detection theory and signal processing, along with various technical analysis indicators. I've worked with many financial platforms and data feeds: Deltix QuantOffice (C#), CQG API, Bloomberg, Interactive Brokers API, MultiCharts (PowerLanguage), MultiCharts.NET (C#), TradeStation (EasyLanguage), FIX (HotspotFx), ITCH (HotspotFx), etc. I can integrate other systems with MATLAB or Excel where there's an advantage. I've created C/C++ .mex files, VBA macros, Java/MATLAB integration, MATLAB/Excel integration. I've been programming in MATLAB since 1990, and can sometimes get it to do things that others can't. I can also translate or port a MATLAB application to other languages, especially Python or C#. I'm located in Southern California. For clients located within 2 hours, I can drive to meet you (sometimes same day, schedule permitting). I'm also happy to work remotely. I'm a US Citizen and have held a security clearance, though it is no longer active. The foundation of every successful project is good communication. If you have a project that needs to be done well, then let's communicate!

    Jonathan Meier Agency Contractor

    Data Scientist/R and Python Developer

    United States - Last active: 3 days ago

    I study Computer Science and Economics in the US. I have been doing statistical data analysis in R and python development for 2+ years now and have experience working with a variety of single/multiple regression and /multivariate time series models, clustering techniques, and survery data. I have also developed a specialty in machine learning techniques, particularly Random Forest, kNN, k-means, C4.5, and CRAN. I specialize in creating meaningful reports and visualizations that allow everyone-even non-statisticians-to understand complex expressions of statistical analysis. Heavy experience using ggplot2 within R. Almost anyone can run a statistical analysis, but it takes skill to craft something that is digestible and easy to understand. I am a dedicated and hard worker, and guarantee a useful product delivered in a timely manner.
