My name is Ulrike Fischer and I live in Germany. I have been using LaTeX for more than 25 years for all sorts of documents. For more than 15 years I have been active in various TeX-related usenet groups, mailing lists and web boards. You can find me e.g. at tex.stackexchange.com. I'm member of the LaTeX-Team. I'm the author of some packages (tagpdf, returntogrid, xskak, chessboard, chessfss, citeall, combofont) and maintain currently the for lualatex important packages luaotfload and lualibs. I have published various articles for the German TeX-group Dante, e.g. in 2008 an introduction to XeLaTeX and in 2014 an article about biblatex variations which has been translated for TUGboat. I had some talks at meetings of Dante, e.g. about biblatex, how to correct errors and expl3, and recently about the tagging of pdf-files .
Currently I use mostly MiKTeX 2.9. and TeXLive 2018 win 10. I also have TeXLive 2012 to TeXlive 2017 and a ConTeXt Standalone for testing purposes. As editor I use mostly Winedt 10.3 but I have also other editors installed.
