PROFILE

Ethan D'costa

Worked across canonical/k8s-snap, canonical/k8s-dqlite, canonical/microk8s, and canonical/craft-parts to deliver features and reliability improvements in Kubernetes tooling and build automation. Developed CLI enhancements such as spinner-based progress feedback and later streamlined the user experience by simplifying command outputs. Addressed cluster integrity by implementing node name validation and expanded integration test coverage using Python and Go. Improved documentation for COS Lite integration and internal processes, focusing on onboarding and operational clarity. Delivered a Bazel Build Plugin in canonical/craft-parts, enabling custom build configurations and Bazel 9 compatibility. Emphasized maintainability, CI efficiency, and robust DevOps practices throughout the work.

Feb 1, 2026

February 2026: Strengthened cluster integrity and reliability in canonical/k8s-snap by implementing a validation that blocks control plane nodes from joining with a name identical to an existing worker node, and by adding integration tests to verify the behavior. The change reduces node-name conflicts, improves onboarding reliability, and lowers operational risk for dynamic Kubernetes clusters. Demonstrated solid engineering discipline with validated code changes and test coverage, aligning with Kubernetes best practices.

Nov 1, 2025

November 2025 performance recap across canonical/k8s-snap, canonical/k8s-dqlite, and canonical/microk8s focused on reliability, networking, and CI efficiency. The month delivered targeted bug fixes, infrastructure improvements, and key dependency upgrades that reduce downtime, improve test stability, and enable faster feature delivery.

October 2025

Oct 1, 2025

October 2025: Focused on improving CLI UX for long-running operations in the canonical/k8s-snap project. Introduced a spinner-based progress indicator and refined activation to run only when explicitly requested via --wait-ready, reducing UI noise and improving perceived responsiveness during Kubernetes operations. This also ensures progress feedback reflects actual readiness checks, improving accuracy and operator confidence.
