Code Wanderer

Definitions

Someone who moves through many code areas without settling permanently in one, often driven by curiosity or necessity. In engineering slang, code wanderers can connect distant parts of a system, though they may also avoid deep ownership.
In plain English: A developer who roams through many different code areas rather than staying rooted in one.
Example: "He was a code wanderer, always useful in unfamiliar corners of the stack but harder to pin down when long-term maintenance ownership came up."
