Have been building software for the web since 2005. Highly value autonomy and ownership. Focused on getting things done. I define myself as a Product Engineer: a full-stack developer with an eye for design and strong product thinking. Lean and agile methodologies practitioner. I thrive in a modern product organization, working in a collaborative, data-driven, multidisciplinary team.
