The go1.27 Goroutine Leak Profile: What Reachability Can and Cannot See

Automattic
Rebuilt the way internal automation tools securely access the company's code repositories, replacing a fragile, manually managed system with a properly scoped, auditable one. Then led the rollout of an organisation-wide system that automatically checks software dependencies for updates and merges safe ones in in, cutting down the manual work engineering teams previously had to do to stay patched and secure.
