Working on the LeanXcale high performance ultra-scalable data store named KiVi .I'm teaching and doing OS research at a University in Madrid. My research (as well as the PhD I did) is mostly on how a distributed system for today hardware should be like. I'm working at the Laboratorio de Sistemas in a new system named Clive. Previously I worked on a few others called Nix, Plan B, Octopus, and others. See http://lsub.org for more details. See also http://syssoftware.blogspot.com.es.I also wrote several database engines for LeanXcale, Ericsson, and others, a few window systems and distributed editors, and a share of kernel code.I am also a PADI divemaster.Specialties: operating systemssystem softwareuser interfacesdistributed systems
