Autonomous Code Refactoring and Self-Healing Infrastructure
Two of the more practical uses of AI in engineering are not new features — they're maintenance work most teams never have time for: refactoring old code and infrastructure that recovers on its own.

Every codebase accumulates debt: the module nobody wants to touch, the workaround that became permanent. AI-assisted refactoring tools are starting to make paying that debt down realistic instead of aspirational.
Refactoring at the pace of review, not rewrite
An agent can propose a refactor, run the existing test suite against it, and surface only the changes that need a human judgment call — rather than a developer needing to block out a week for a rewrite that keeps getting deprioritised.
Infrastructure that repairs itself
The same pattern shows up in operations: systems that detect a failing service, roll back or reroute automatically, and alert a human only if the automated fix doesn't hold. The goal in both cases is the same — remove the toil, keep a person in the loop for anything that actually needs judgment.
