Yesterday was my last day at Twitter. I left to start my own company. What I'll be working on is very exciting (though I'm keeping it secret for now).
Leaving Twitter was a tough decision. I worked with a whole bunch of great people on fascinating problems with some of the most interesting data in the world. Ultimately though, I felt that if I didn't make this move, I would regret it for the rest of my life. So I put in my papers about a month ago and then spent a month transitioning my team for my departure.
This ends an eventful three years that started with me joining BackType in January of 2010. So much has happened in these past three years. I open-sourced Cascalog, ElephantDB, and Storm, started writing a book, gave a lot of talks, and in July of 2011 experienced the thrill of being acquired. My projects spread beyond BackType and Twitter to be relied on by dozens and dozens of companies. Through all this, I learned an enormous amount about entrepreneurship, product development, marketing, recruiting, and project management.
