PROFILE

Emily Shepherd

Worked on backend and infrastructure improvements across cilium and cri-o repositories, focusing on system resilience, documentation accuracy, and load balancing reliability. In derailed/cilium, addressed endpoint lifecycle stability by ensuring endpoints unlock correctly during IPIdentitySync failures, using Go and robust error handling to prevent deadlocks from transient network issues. For DataDog/cilium, implemented namespace-aware EndpointSlice naming and regression tests to avoid cross-namespace collisions, and clarified kernel configuration requirements in documentation, enhancing user setup and code safety. In cri-o/cri-o, improved configuration management by correcting seccomp_profile documentation, reducing user confusion and aligning guidance with actual security behavior. Work emphasized maintainability and operational correctness.
