I am an economist, self-taught programmer, BI lead, author, lecturer and R enthusiast. I enjoy programming, writing and teaching. Focus of my work is on making complex things more accessible.

My GitHub presence features the R packages I have developed over the last couple of years. They broadly fall into the following categories:

• Statistical methods and teaching (packages quantification and xplain)
• Data import and export (packages flatxml, xml2relational, xmlconvert, refreshr)
• Working more efficiently with R (packages packagefinder and debugr)
• Enhancing the R language (packages pointr, switchcase, typehint)
• Shiny (shinyfilter)

I run the Topics in R blog which I mainly use for announcements (new packages, articles, books) and which also feeds into RBloggers. Here are the most recent posts (at least the major ones):

• Converting XML data to R dataframes with xmlconvert
• Pointers/shortcuts in R with the 'pointr' package
• The 'xml2relational' package: Transforming NoSQL to relational data
• A switch-case construct for the R language
• Finding CRAN packages right from the R console

I try to keep away from social media (Github != social_media) to protect my time and be more productive, but I do use Twitter. If you want to receive the latest updates on my packages and learn about interesting things I come across, click @jsugarelli to follow.

• Reviewing the English translation of my German Python & JavaScript introductory textbook (publisher: Springer)
• Giving lectures in economics at Hochschule München

Mainly

but also from time to time

Generally, I like to try out new (or old?) things (ever written something in FORTH?)

For the tool freaks out there: My editor/IDE choice is quite language-dependent. I work mainly in R Studio (for R), Microsoft SQL Server Management Studio (for T-SQL), Heidi (for MySQL), and DBeaver (for Postgres and everything else). I also use Sublime Text (mainly for JavaScript, Perl and PHP code) as well as PyCharm (for Python). To organize everything I work with Microsoft To Do and Microsoft OneNote (my second brain, absolutely indispensable). And most importantly for efficiency and avoidance of frictions: I use the same tools at home and in my job.
