Professional Experience

07/12-present
SHMsoft, Houston, TX
Software architect & CEO. Involved in a number of Big Data / Hadoop projects in eDiscovery, search, marketing, and training.
Latest clients included Cognizant for multiple projects, Intel for Hadoop training and POC projects for Intel's clients, and Bank of America for Hadoop administration.
Some of the accomplishments were:

Created three training courses: Hadoop for Developers, Hadoop for Administrators, and HBase for Developers. The courses included general overviews and hands-on exercises, also created VM's for that;
Delivered the training to internal Intel groups and to Intel's client. The course were usually followed by the Proof Of Concept implementations in the Big Data areas covered by training;
Delivered the training to other trainers who then delivered them further.
Maintained Hadoop clusters for dev/staging/production.
Created scripts to form EC2 clusters for training and for processing.
Designed action monitoring system for a large cluster in the hundreds of nodes.
Application performance optimization for a Cassandra cluster.

Technologies used on these projects: Java, Hadoop, Hive, Pig, HBase, R, Sqoop, Flume, Maven, Git.

Endorsement from a large corporation IT department person on the training course:

"Regarding your teaching, first let me mention that I'm always honest-- even if it hurts peoples feelings. So perhaps you will be grateful to know that I enjoyed your classes and your presentation style. I liked that you were knowledgeable so you did not need to just read the slides and you were able to deviate from the slides when there were related questions from the audience. When a presenter just reads from the slides I get bored because I'm thinking I can just read the slides and the presenter is not needed. I also liked the many hands-on labs. That is how people learn, not just absorbing info from the slides but applying it. I would recommend you as a presenter on Hadoop technology and will recommend you for training at my company if / when we decide to support HBase in a production setting."
