SUMMARY:

Experienced and versatile Lead Hadoop Administrator who provides expertise installing, configuring, deploying and administering small to large - scale environments. I have a MapR Hadoop Administrator certification that I am current on. Also experienced in planning, designing, setup, and configuration of infrastructure platforms using Dell, IBM, and/or Confidential UCS blade systems. Key areas of strength: design, implement, and operate experience with a MapR Hadoop infrastructure running MapR Tables (HBASE), Pig, Hive, Spark, Mesos, and Elastic Search.

Strong technical skills blend with interpersonal skills, a customer service attitude and the ability to manage multiple assignments efficiently under pressure while meeting tight deadlines.
