David Batanero enjoys telecommunications. He is currently the anti-fraud manager in a multi-national telecommunications company where he plays with the bad guys and carries out research. He has given talks at G-Con II/III, in Mexico in 2003/2004, at uCon, in Brazil in 2009, at t2 in Finland in 2009, at EISI III in Colombia in 2009 and at Ekoparty in Argentina in 2015. Ever since he was young, he has enjoyed disassembling and toying with any device he comes across, even if he might end up with left-over components when it needs to put it back together again. He is a tireless traveler, though his goddaughter calls him the "crazy uncle."
