    Matthew S.

    Experienced Programmer (PHP, CodeIgniter, jQuery, C++, Qt)

    United States - Last active: 2 days ago - Tests: 2 - Portfolio: 5

    I consider myself a fairly decent programmer. I'm fluent in web and software application programming. Lately I've been involved mostly in web applications (using PHP). I'm more suited with web application (getting things working - and well) rather than web design (making things look pretty). The projects I've been involved with used PHP/CodeIgniter along with jQuery for browser scripting. I've also done some work with WordPress plugins. I'm also adaquently experienced in software applications. Programming stuff for Windows and Linux using cross-platform toolkits namely: Qt and wxWidgets. I've also done some low-level GUI stuff using Simple DirectMedia Layer (another cross-platform toolkit). I like computers, enjoy programming and like the challenge of coming up with good software solutions.

    Philippines - Last active: 1 day ago - Tests: 11 - Portfolio: 9

    I am an independent graphic design professional doing logo and brand identity design including web/app/ui and print design. I started full-time freelance graphic designer in 2005 doing print design works for local small advertising businesses, small entrepreneurs in my province. My work ranges from posters to large print design, packaging/label design and logo design. Few years before 2005, I have also worked as part-time graphic designer for a politician designing campaign posters, banners, computer wallpapers, logo and ID design to it's political party. I am a self-taught designer. I respond well to a challenge and enjoy the rewards of hard work and dedication. I am an undergraduate computer science student - during my college years, I have gained knowledge and skills on HTML and CSS aside from programming languages I used to love. I follow my passion for art, design and love for my work when I begun working online full-time from 2007 doing logo, graphics and web design. I have honed my skills on logo and brand identity over the years. I also do and love painting, which I hope to continue again. Until now, I continue learning design and in the previous years I have worked further on UI design- web and mobile. I have front-end web design/development experience as well as designing mobile app UI for android and IOS devices. https://www.behance.net/bobsagun | http://bobsagun.com

    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.
