    Data Science | Statistics | R Programming

    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 www.immobilienscout24.de, 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.

    Scott S. McGeary

    BI/Reports Architect

    United States - Tests: 2 - Portfolio: 4

    With 16 years of experience in the public and private sector, I bring a vast spectrum of experience from many platforms and technologies. I started my career doing web development for several years and migrated into data warehousing, reporting, data management, data automation, and pretty much anything you can think of that deals with data. The Microsoft SQL Server BI Stack is my wheelhouse, but I use many other tools beyond SSIS and SSRS, such as Tableau and Crystal Reports. I enjoy solving extremely complex data issues with my skill set. My passion is making data "work" for my clients. I still do a bit of web development for clients and am very proficient in Classic ASP web apps. Let's talk about your project and see if I am a good fit!
