He is very pro-active, resulting in delivering work of high quality in a timely manner.

He would prove to be a great asset in any team.", "John and I worked together through the acquisition of Fitbit by Google. What stands out about John is his ability to understand large systems quickly and apply his understanding to then help the business solve a critical problem. Examples include: - migrating off of AWS and into Google Cloud - migrating from self-hosted mongodb to fully managed MongoDB Atlas - transforming Google Cloud services using Cassandra to internal google services and databases In each, the problem presented itself as ambiguous and John was able to tease it apart, design solutions, and implement them. John builds community in the workplace by volunteering to lead and work with wide groups of peers on events ranging from hack-a-thons to classes on effective presentations.", and "I worked with John on a node.js based server project.
