As a senior software engineer team lead at Human Interest, I design, execute, and oversee highly visible, cross-functional engineering efforts, using domain driven design best practices and service oriented architecture. 

I am also one of the top producing individual contributors, consistently completing tickets at high velocity while acting as a technical consultant for other teams. I bridge knowledge gaps and communication between engineering and product. I have a bachelor's degree in computer science from University of Oregon, and I am AWS Certified. I have a particular interest in cloud technologies, and I enjoy working with Node.js, Typescript, React, GraphQL, and PostgreSQL.
