Nigel McNie began his career in free software when he was just 17, working part time as an intern at Catalyst IT. His first contribution to the free software world was the popular GeSHi syntax highlighter, which can be found to this day highlighting source code on sites such as Wikipedia. In 2005, he dropped out of university to work full time, and began on the Mahara project in 2006. Now, Nigel leads development on the project, and has designed and co-written large parts of the codebase, including the Views framework and LEAP2A support.

Heinz Krettek is a German teacher at a school for vocational education. He studied business sciences and sports. His main job is to prepare socioeconomically deprived students for lifelong learning. In 2006 he discovered the portfolio work and began to translate the German langpack for Mahara. The first translations for Mahara 0.6 were published on his own Moodle site. Soon after Nigel McNie installed a git repository the actual files were published in the Mahara git.

He organized several education and training sessions for teachers and was speaker at the German moodlemoots. Since 2008 Heinz has been partner of a company that offers LMS hosting and Mahara hosting. His company is the official German Mahara Partner.

He lives with his wife and the four kids in the Black Forest. In his spare time Heinz prefers the 3 M's: Mahara, Moodle, and marathon. He finished the New York Marathon. His motto is: who finished a marathon will struggle all problems in school ;-)
