    Data Scientist and R Expert

    United States - Last active: 1 day ago - Tests: 7

    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.

    Senior Programmer & Numerical Modeller

    Spain - Last active: 10 days ago - Tests: 4

    My name is Alvaro (nickname: varocarbas) and I am a senior programmer (+7 years), who has participated in a wide variety of projects involving custom software development and numerical modelling. I have recently reopened my 1-person company: Custom Solvers 2.0. My favourite programming languages are: - Desktop-based: C# & VB.NET (mainly Winforms); VBA (MS Office Macros) & VB6; Java and other C-based languages; FORTRAN. - Web-based: PHP & JavaScript; ASP.NET (C# & VB.NET). Customsolvers.com 2.0 references: - About me (varocarbas): http://customsolvers.com/en/pages/varocarbas_com/local/about/. - About Custom Solvers 2.0: http://customsolvers.com/en/pages/company/basic_information/. - Principles: http://customsolvers.com/en/pages/company/principles/. Mainly interested in fixed-price projects over $1000. NOTE: this was one of the freelancer-network profiles (although not precisely the most important one) which was associated with the previous version of my 1-person company (trendingIT/Custom Solvers). In 2015, I tried to create a new profile for Custom Solvers 2.0, but UpWork didn't allow me to do so (even though I proposed them different alternatives, logically by avoiding the deletion of this old account. And I certainly don't like unreasonable inflexibility...). In summary: Custom Solvers 2.0 will also be using this profile.

    Senior developer, Project Manager

    China - Last active: 5 hours ago - Tests: 9

    Professional and hobbyist developer, with over 15 years of actual development under the belt and 6 years in 'hands-on' management positions (as engagement manager in a consulting firm and then as a CTO in a web startup). My technical experience ranges from desktop (C/C++/C#/Java/VB, scripting in Python/Ruby/VBA), embedded (PIC, ATMEGA, ARM), web (PHP, Ruby on Rails, JS/Coffeescript, HTML5 and some understanding of web design principles and UX construction) and ERP/Business Intelligence (SAP BW, QlickView). These days (2014), I am mostly doing web dev (front-end/back-end) in Ruby, Python and CoffeeScript - they allow very quick iterations and cutting through tons of boilerplate to get to a MVP as quickly as possible. My skills in C/C++ are a bit rusty, but I'll gladly dust them off for an interesting project :) I read Java and C# and don't mind using them as external dependencies, but I do not enjoy working with those. As for my management experience, I have been leading small and large engagements (up to 2 millions EUR) in offshore settings (India, China), both on-site and remotely I feel like I have a good understanding of the communication and management challenges involved in freelancing. As your contractor, I see myself adding value by challenging your requirements, helping you define clear specifications and, if the assignment is large enough to need more than myself as a developer, I can help you screen out other offshore resources and simplify your outsourcing experience.
