Mongo Machine
Developed a SaaS platform from the ground up to provision, manage and serve MongoDB instances as an "on-demand" service. In a little over a year I not only took the company to well into profitability, but also became an expert in NoSQL databases and DevOps/Chef/Cloud provisioning. Company has a successful exit with an acquisition by MongoHQ in July 2011.
