I'm a fairly junior engineer at a subsidiary of one of the big 4. Before that, I was at a well-known big box store working on a few different projects.
The most impactful thing I delivered at my previous company was a script that moved all of our team's data from a self-hosted db to something on company cloud that was a lot more stable. The script itself wasn't very complicated (essentially just mongodump and mongorestore), but it made a big impact on ensuring that our team's dataset search tool would continue to be accessible to regulatory compliance folks. In turn, the regulatory people could use the tool to protect the company from getting fined under CCPA, etc.
It made a pretty big impression on me that something incredibly simple like that could make as much financial impact in expectation as that script did. Now when I mentor interns and newer, more junior people, I always tell that story as an example of how high impact can be surprisingly uncomplicated.
