Hi! 👋

I am currently working on one of's 15 repos, a class by FeM, Wes Bos, or a personal coding project.

I am currently learning/refreshing on frontend development (e.g., HTML, CSS, JS) and engineering config (e.g., automated testing, CI/CD).

Ask me about open source software (OSS) coding practices, federal open source policies and practices, frontend engineering topics (i.e., coding, config, testing), or academic pursuits and navigation (I was in school for 32 years, elementary to PhD, eeks!).

You can reach me by email, Twitter, and LinkedIn.

Fun facts include having an awesome family, serving in the US Army and being deployed, working at the White House (Obama Administration), obtaining a PhD, and often training and racing in an ultra-endurance mountain bike or running event (resume, just in case 😉 ).
