i've worked almost 2 decades in industry. from an intern working on cad/cam systems, to shipping and receiving applications in OS/2, AIX, and CICS, to operations, to system admin research and java frameworks at IBM Almaden Research (11 years), until finally arriving at Yahoo! Research (3 years ago) to work on the largest (and therefore coolest) distributed computing problems. my main interests now are large scale processing environments and highly available and scalable systems. i've worked quite a bit in open source: i wrote and maintained the linux aironet wireless driver years ago; my research project at ibm grew into osgi (i think some of my code is still there) which is now in application servers, ides, cars, and mobile phones; two projects i worked on in research, Pig and ZooKeeper, are apache projects for which i am a committer.
