Profile: https://flows.cv/peterpanteraarzhintar

All-around nerd and software engineer experienced in building web applications from the ground up using agile methodologies. I love working in small cohesive teams -- culture matters immensely when building a productive environment.

I focus on product (who uses it and how) when tackling technical hurdles. I love pair programming, test-driven-development, and shipping small features to build up to a great product.
