R & R Shiny Expert – Data Scientist
Summary
Expertise in R, R Shiny, deployment of APIs and Shiny apps at scale.
Three areas of expertise:
• Developing R scripts and building Shiny apps from scratch.
• Optimizing, maintaining, fixing, and cleaning R packages.
• Coaching and training individuals with R Programming.
I help companies developing R scripts and deploying them in production through an API or a Shiny app on a server. I take great care in producing clean, performant, and robust code.
With a proven capability to work independently and in teams, mentor co-workers, communicate with both technical and non-technical audiences, I consistently deliver value to a variety of clients.

Experience
Rudy Pastel Consulting, Germany, Europe. 02/2018-today
— Munich Re, one of the world’s leading reinsurers: developed an ETL software to replace Microsoft SSIS and enable all team members to quickly import data.
— Symrise AG, major producer of flavours and fragrances: built a data driven replicator of chemical compounds and embedded it in a dashboard. Flavorists now build on the mathematically best point instead of their guts feeling, which saves time.
— Lowell Financial Services GmbH: built a debt collection forecast model and embedded it in a dashboard. Accountants can now reliably fulfil their regulatory obligations in a few clicks and two hours instead of weeks of guess-work.
Tools: R, devtools, testthat, roxygen2, httr, Rcurl, Rmarkdown, R-Shiny, SQL, git
