Stuart loves storage (130 PB at Criteo) and is part of Criteo's Lake team that runs some small and two rather large Hadoop clusters. He also loves automation with Chef because configuring more than 2200 Hadoop nodes by hand is just too slow. Before discovering Hadoop he developed user interfaces and databases for biotech companies. Stuart has presented at ACM CHI 2000, Devoxx 2016, the NABD Conference 2016, Hadoop Summit Tokyo 2016, Apache Big Data Europe 2016, and Big Data Tech Warsaw 2017.
