Nolan Chan

As a Senior Software Engineer, I have led remote development teams in Brazil and LA on several features, such as Docker and Kubernetes implementations, enterprise development tooling, and various full-stack features. I enjoy driving the adoption of remote culture on my team, introducing one-on-one meetings and new team initiatives.
