Profile README

Hi there! 👋

I'm a senior software engineer on the Shiny team at Posit where we build tools that enable data scientists to more easily develop analytical websites. In addition to contributing to Shiny and the Shiny stack/ecosystem (e.g., htmltools, htmlwidgets, sass, bslib, etc), I also maintain the plotly R package and have done so for many years.

I also:

📚 Wrote a book, "Interactive web-based data visualization with R, plotly, and shiny"

💼 Consult to help keep my applied data science skills sharp

🏆 Have a PhD in statistics and have won awards for my contributions to the field.
