Professional Experience

I am an experienced software engineer with a passion for developing applications using new and innovative technologies, contributing to projects including Spring REST Docs, Codenarc, Apache Groovy, and Gradle, and sharing knowledge about technology. As a conference speaker, I have made appearances at the Grace Hopper Celebration of Women in Computing, SpringOne Platform, JFokus, Devoxx Belgium, and many others. My strong ties with the developer community including running the Groovy Community Slack Team and leadership experience within several organizations including as a founder of GR8Ladies (now GR8DI) make me a better Developer Advocate.
