Challenge Hunter (Technology + Human Behavior + Data)

United States

***If you know exactly what needs to be done and don't think there's room for improvement on how it's going to be done, or if you consider the project to be easy or not particularly important, do not contact me or bother reading any further.*** I'm looking for interesting challenges that involve humans, computers, and data to test my understanding. I'm currently most interested in data visualization projects and higher level "systems analysis" projects. But, I'm always interested in problems where someone's well-being is affected. (if necessary, My Rate = Base Rate / (interesting-ness * importance)) Since graduating from MIT Engineering in 2009, I have been working a stream of challenging projects: founding startups, building web applications, marketing technical services, and on and on. Overall, I like to focus on answering the question, "how can we design better Systems to get what we want?" And in thinking about this I've amassed a lot of useful skills and knowledge in both software and just understanding how the world works (and doesn't work.) The more uncertainty you have on what needs to be done, the more help I'll be able to be. I'm very likely the most creative guy you'll ever meet, and what I like to do for fun is think and work on challenging problems.

Germany - Tests: 4 - Portfolio: 3

I have a PhD in Cognitive Science and a MSc in Computational Linguistics, as well as several years of experience in statistical data analysis and software development in R. I have developed software in pure R as well as in C/C++/Rcpp, with a focus on the implementation of machine learning algorithms and statistical techniques. I enjoy understanding all kinds of data, as well as helping others understand it and convert it into actionable intelligence. I am particularly interested in churn analysis and statistical consulting regarding usability studies or A/B testing in advertisement and e-commerce. I have experience in analyzing and reporting on data from sectors as diverse as psychology, education, health, finance, SEO and E-commerce. Most recently, I have analyzed online user behavior for, and created a Bayesian model of conversion and profitability to manage campaigns on Google Adwords. I specialize in churn analysis and survival random forests, but I can help you with anything from simple ANOVAs or linear mixed effects models in lme4 to Bayesian methods in RStan.
