Karen Huaulme
Karen Huaulme
MongoDB, USA
As a Principal Developer Advocate at MongoDB, Karen Huaulmé (pronounced “You-Old-Maid” - but with no d’s) develops and presents applications to help developers unleash their creativity across all aspects of data and technology. Leveraging her past experience as a Solutions Architect for some of MongoDB’s most demanding customers, Karen loves to trigger that “aha” moment in the minds of developers - when they recognize a better path to simplify, enhance, and accelerate their projects in ways they never thought possible. Prior to MongoDB, Karen spent most of her career working with video game developers as a Solutions Architect and Integration Engineer at Nvidia, Amazon and Twitch. In her free time, Karen embarrasses her 2 kids, spoils her dog, and feeds her addiction to adventure travel - not necessarily in that order.

Amy Bass
Amy Bass
Docker, USA
As a youngster, I had an early interest in computers. I quickly learned to disassemble and reassemble my family's Tandy 1000 without much effort. This passion only grew as I got older. In college, I became very interested in helping to bridge the growing digital divide and started a student organization, Tech Serv, at Drexel University. After college, I started my career as a data analyst but quickly found a career in Product Management. Here, I was able to combine my love for technology with my passion for improving the lives of others. Since that time, I've been a product manager in a variety of industries including MarTech and HealthTech. Now at Docker, I hope to continue on my journey by improving the lives of developers and helping solve their daily challenges.
