Barry Hart began using Storm in 2012 at AirSage. He quickly saw the potential of Storm while suffering from the limitations of the basic storm.py that it provides. In response, he developed Petrel, the first open source library for developing Storm applications in pure Python. He also contributed some bug fixes to the core Storm project.

When it comes to development, Barry has worked on a little of everything: Windows printer drivers, logistics planning frameworks, OLAP engines for the retail industry, database engines, and big data workflows.

Barry is currently an architect and senior Python/C++ developer at Pindrop Security, helping fight phone fraud in banking, insurance, investment, and other industries.

I want to thank my wonderful wife, Beth, for all her love and support. I would also like to thank my two little boys, who keep me young and make every day special.
