I was lucky enough to spend the last four years of my life working with an incredible team of people on the Twitter Platform. I joined Twitter in June of 2009, shortly after Alex Payne had launched and built the early community around the Twitter API. While my role initially entailed product and engineering management, I spent all four years focused on building an ecosystem of companies that created value for our users and our partners and that’s where I’ll focus these posts. It was my first time doing anything like it and I learned an incredible amount through trial and error. There were failures, triumphs, and great lessons learned along the way.
