• Hired/trained/managed a team of five to allow for quicker growth. • Took a somewhat chaotic server environment of 200+ servers and streamlined the release, monitoring, installation process via automation tools (fabric,puppet) while building out the company's first self-managed data center installation. Managed all facets of activation from product/vendor selection and procurement to installation of hardware and network. • Implemented new data solutions for new products based on MongoDB and Vertica. These implementations allowed real-time insight to data that was previously unavailable
• Rebuilt a complex, aging environment with modern software principles. • Redesigned entire data serving architecture with a MySQL based master/slave architecture.
