My name is Casey Stella and I write software for a living. This is my little segment of the Internet. I hope you enjoy learning a bit more about who I am, what I do and what I think.

About Me

I have tended to specialize in writing software and solving problems where there are either scalability concerns due to large amounts of traffic or large amounts of data. It makes a lot of sense, therefore, that I’m currently with Hortonworks as a Principal Architect with a special focus on Data Science. I spend time with a variety of clients, large and small, mentoring and helping them use Hadoop to solve their problems.

Before, I was very proud to work at Explorys doing data mining and medical informatics using Hadoop and HBase. I learned a lot about Hadoop, HBase, data mining, medical informatics, data architectures involving unstructured data, machine learning, statistics and much more working there. I lead the effort to begin open sourcing some of our Hadoop and HBase utilities called Project Apothecary.

Prior to that, I’ve worked in a stealth startup architecting and writing server infrastructure for VOIP using .Net and Cassandra, the Oil Industry writing signal processing algorithms for seismic data and at Oracle writing Oracle Enterprise Repository.

In a galaxy far, far away and a long time ago, I was a graduate student at Texas A&M under J. Maurice Rojas in the Department of Mathematics. I was in the PhD program, left with a Masters and a deep interest in Mathematics.

At night, I work on a variety of personal projects involving machine learning, natural language processing, efficient distributed subsequence querying using Dynamic Time Warping, and much more. Also, I sleep sometimes.


I keep a technical blog.
