Gulsum Atici engineered robust enhancements across the canonical/sdcore-k8s-operator and oai-ran-du-k8s-operator repositories, focusing on Kubernetes operator development, CI/CD automation, and secure deployment practices. She stabilized gRPC connectivity and improved deployment reliability by upgrading container images, implementing TLS, and aligning documentation with evolving tooling. Leveraging Python and YAML, Gulsum introduced advanced RF parameter calculations and expanded configuration options for RAN deployments, while also standardizing static analysis workflows using GitHub Actions and TICS. Her work emphasized dependency management, automated testing, and system design, resulting in more secure, maintainable, and production-ready telecommunications infrastructure with improved release quality and observability.

April 2025: Delivered standardized TICS static analysis workflows across the canonical sdcore-k8s-operator family, upgraded CI to shared workflows v2.3.2, added tics.yaml scheduling, and enabled XML coverage reporting. Implemented weekly TICS scans, delivering automated quality checks, improved security posture, and faster, more reliable releases.

February 2025 performance highlights: Stabilized integration and deployment reliability across the OAI RAN Kubernetes operators, advanced RF parameter calculation capabilities, and expanded deployment configurability. Key outcomes include deterministic test environments through dependency pinning, the DU RF parameter calculation suite with unit tests, new DU deployment configuration options, and updated deployment documentation. These efforts reduce production risk, enable faster rollouts, and demonstrate proficiency in dependency management, unit testing, charm/configuration, and documentation.
