I'm located in Copenhagen, Denmark
I'm the main developer of [uCore], a enterprise development system for business applications. Lua is used as the programming language of uCore. To raise the stake even higher, most of uCore is written within uCore itself.
In the 3.2 days, I created a distribution of Lua that supported multiple states. This is now standard in the 4.x version.
At this point, we have one application released [VelociPOS] - a complete POS (Point Of Sale) system.
Currently I'm using Lua for the robot Crazy Ivan.
Thank you Erik for giving me the kick that resulted in lua-users.org and this wiki. --JohnBelmonte
