I am the founder of Concurrent, Inc., and the author of Cascading.

Cascading is an application library for rapidly developing highly complex large-data processing systems. Here are case-studies of some of the problems people use Cascading for.

Concurrent was funded in 2011 to grow the Cascading community and build products to ease the management of complex data processing systems. Of course we are hiring.

I am also the author of the Scale Unlimited Apache Hadoop BootCamp, the first commercial Apache Hadoop training course. Training customers include Apple, Sun Microsystems, Hewlett Packard, and Orange Telecom and has been delivered across the US, UK, Europe, and Asia over the last 4 years.

See my LinkedIn profile for a detailed work history and the technical advisory roles that I have held.
