Work History

April 2026

11 Commits • 5 Features

Apr 1, 2026

During April 2026, we delivered hardening and modernization across deployment-operator and console. In deployment-operator, we fixed a bug to preserve user-specified images for default containers and added a unit test, upgraded Helm to v3.20.1, and enhanced cluster distribution inference with a priority mapping to reduce ambiguity. In console, we introduced Monitor State visualization via a new AlertStateChip and added a Kubernetes deployment pathway for Plural via Helm with PostgreSQL, RabbitMQ, and InfluxDB, including monitoring and scaling configurations. These efforts improve reliability, deployment safety, observability, and scalability, delivering tangible business value by reducing misconfigurations, enabling efficient deployments, and improving operator visibility. Technologies demonstrated include unit testing, Helm, Kubernetes, UI component design, and observability tooling.
