I am the Tools project lead for VisualWorks, a Smalltalk implementation. Since 1992, my professional life has been tied to Smalltalk, however I am also intimately familiar with Lisp, in particular Common Lisp, ML, Haskell, Java and a bunch of scripting languages I consider too much of the same to name here separately.
I have a somewhat neglected blog and a page on VisualWorks wiki.
