I have given numerous talks and workshops, at WhyR 2020 using NPM and webpack with R, a workshop on building htmlwidgets at eRum 2020, as a guest on the Shiny dev series podcast discussing user experience, and many more.

I am also the author of the book JavaScript for R published by CRC Press as part of the R series.
