One of the things I'm most proud of is the long-term impact I had while working at the NSA -- organizationally, culturally, and pedagogically. When I arrived there and began working as an analyst, the civilian software engineers would build tools for analysts, and those active-duty analysts would use those tools to do their work. Because of cultural differences between federal civilians and military personnel and the way the engineering and analytics are treated as orthogonal to one-another organizationally, there was very little communication between the two teams.
Once I started working as part of the engineering team, I helped bridge that gap in communication between engineering and analysts. In fact, that collaboration was so successful, NSA Hawaii made it a point to create a new role within engineering specifically for a military analyst to work as a software developer and began creating a training pipeline for the role as I was leaving.
