Biography

Stuart Mitchell began Brazilian jiu-jitsu under Douglas Santos in 2003, while building an academic career in engineering science. He later co-founded Auckland BJJ with Serge Morel, teaching alongside a professional life in programming and optimisation. Born in 1976, Mitchell’s academy biography describes his New Zealand birthplace and family connections to Levuka in Fiji through his mother and Glasgow through his father. His personal CV records a University of Auckland engineering-science doctorate completed in 2004. He lectured in the university’s Department of Engineering Science from 2002 to 2008, then held a research fellowship from 2009 to 2011. His professional work addresses how organisations make decisions, using programming and optimisation to improve their operations. He dates freelance consulting from 2011 and work with Day 8 Technology from 2014. On his personal site, he identifies himself as the maintainer of PuLP, an open-source optimisation tool, and a contributor to re-frame, a framework for building interfaces with ClojureScript. His personal jiu-jitsu page preserves a separate part of that period: a brown-belt division win at Brazil’s Santa Catarina State Championships, accompanied by links to his semifinal and final recordings. Auckland BJJ dates his black belt to December 2011. Mitchell and Morel started the club that year in a corner of David Tua’s boxing gym in Onehunga. Mitchell’s older account of their introductory classes describes a mixture of drills, technique instruction and free sparring. Students moved from practising material into trying it against a partner in an unscripted exchange. The club relocated to Rick Littlewood’s Epsom dojo in 2012, opened another site in Sandringham in 2018 and brought the two locations together in Onehunga in August 2020. The academy identifies Mitchell as a third-dan judoka and describes his BJJ teaching through grip fighting, leg entanglements and the details of sweeps, the reversals that bring a bottom player on top. He teaches regularly and runs gradings. His public Beltchecker profile, linked by the academy, displays fourth-degree black belt, while the academy biography lists third degree. Auckland BJJ credits Mitchell and Morel with awarding Luiz Machado his black belt in 2020; Machado now teaches at the club alongside its founders.
