PROFILE
Charlie Kenney
Worked on the cilium/cilium repository to enhance NodeManager reliability and improve CI test stability. Focused on backend development using Go, addressing issues with premature pruning of local cluster nodes and ensuring node metrics accurately reflected the current management state, especially after restarts. Introduced targeted changes to node lifecycle handling, which improved cluster stability and telemetry accuracy for operators. Additionally, stabilized CI by replacing a deletion-wait pattern in node state validation tests with a polling-based approach, reducing flakiness and enabling more deterministic test outcomes. Demonstrated skills in distributed systems, system programming, and CI/CD, contributing to more reliable automated testing workflows.

Sep 1, 2025Month: 2025-09 focused on stabilizing CI reliability for node state validation in cilium/cilium. Delivered a targeted fix to reduce flaky tests by replacing the previous pattern of deleting the node state file with a polling-based approach that reads until the expected state is observed or a timeout occurs, enabling reliable test execution under concurrent node events. This change reduces CI downtime, raises confidence in PR validation, and accelerates feedback loops. Tech work included adding polling logic in the test harness and updating test expectations to align with concurrent node transitions. Impact: fewer flaky runs, more deterministic test outcomes, faster iteration on core changes. Technologies/skills demonstrated: - Go and test harness development for concurrency scenarios - CI instrumentation and reliability engineering - Debugging under concurrent events and system state changes - Strengthening release velocity through more stable automated tests.
