Kris Bell is a Scottish pirate and wannabe musician, part–time photographer, avid traveler, open–source advocate, miscreant techie dweeb and a principal Tango contributor. He enjoys swimming, cycling, sailing, occasional hikes and recently took up rock climbing. Previously he dabbled in a bit of car–racing and skydiving, and once took a flying–trapeze course where the latter served only to cement his vocation of choice. He currently lives in California, though hails from the Scottish West Coast and has a dodgy set of Bagpipes to remind him of home. Kris has a varied background in engineering and architecture, spanning application–servers to RAD toolsets, embedded–OS to graphics engines, workflow to high–performance clustering & failover substrata. Some commercial systems he’s designed/built include enterprise & Internet application–platforms, factory–automation systems, carrier–grade middleware, immersive environment–simulation and crazy interactive–clothing. In a different age he would probably have been a steam–locomotive engineer, a swashbuckling jolly–roger, or a funky bell–ringer.

Lars Ivar Igesund holds a Msc in Computer Science from NTNU (Norwegian University of Science and Technology), being involved in the introductory programming course team during that time. Outside of the university, he has worked with network administration and support in both public service and private sector, and helped develop 3D graphic systems in C/C++. He is currently selling consultant services through his own company, Igesund Enterprise Software, doing both D and Java projects. Lars Ivar has been involved in the D community since 2003, and part of the Tango project lead since 2006.

Sean Kelly, a C++ programmer with over 15 years experience that includes several programming languages, is co–founder of the Tango standard library for the open source D Programming Language. He has reviewed articles and books on C++ written by Matthew Wilson, such as Imperfect C++. As a life–long gamer, he is designer and developer of a Neverwinter Nights add–on that provides dynamic inter–server portalling and event propogation. Kelly currently works for Advent Software and lives with his wife and three cats in Concord, California.

Michael Parker, originally from Atlanta, Georgia, found himself in the Republic of Korea as a U.S. Army medic in the summer of 1991. After volunteering for two more tours in Korea, he left the Army in 1994 to teach English in Seoul. In the intervening years, he has taught English in a variety of environments and has occasionally worked in different capacities for the U.S. Government and government contractors in Korea. In the late ‘90s, Mike took up game programming as a hobby. Eventually, his passion for software development expanded beyond games and he secured a series of J2EE web application development contracts with several small Korean companies. He discovered D in 2003 and a few months later created the Derelict project at Dsource.org. He became involved with Tango in the fall of 2006. Currently, Mike is developing his first commercial computer game. He continues to teach English part time in Seoul, Korea, where he lives with his wife Mi Kyoung and their dogs Charlie, Mini, Joey and Happy.
