I'm Nathan Marz. I was the Lead Engineer at BackType before BackType was acquired by Twitter in July of 2011. At Twitter I started the streaming compute team which provides infrastructure that supports many critical applications throughout the company. I left Twitter in March of 2013 to start my own company (currently in stealth).
I'm working on a book called Big Data: principles and best practices of scalable realtime data systems for Manning Publications. The early access edition is available here.
I'm always happy to give advice or connect with people doing interesting work. I welcome you to contact me directly at firstname.lastname@example.org.
