I built the infrastructure connecting DigitalOcean's hosted MongoDB product with the Let's Encrypt certificate API. This provides a better user experience by simplifying the process of connecting to a database.

On the Data Infrastructure team, I've been leading the transformation of HubSpot's collection of MySQL instances into a full database-as-a-service offering for our product developers. We're leveraging Vitess, a distributed data store from YouTube, to move into Kubernetes to cut costs at the same time as we become more flexible. I've made many contributions to Vitess itself as we adapt it to fit HubSpot's needs. I've designed and implemented a certificate-based authentication and authorization system for our fleet of microservices, leveraging HashiCorp's Vault. And I've been the primary communicator of both the vision and details of these changes to HubSpot Engineering as a whole and the individual teams involved. See my KubeCon talk below.
