I worked with someone like this at my first job out of college, he did build a lot before leaving the team. But what he left behind in our systems was a string of technical decisions that really hamstrung us, like building our core service around the API of an extremely inefficient protocol buffer library he wrote himself, resulting in a service that could only handle 4-5 QPS per node. One of our other services used an application specific enum that for some reason existed in its own separate RubyGem that he published, so in order to update it we had to update the gem and then change the dependency reference.
