February 2026: Implemented OpenSearch Charm SMTP integration enabling automatic creation of SMTP configurations when the smtp-integrator relation is established, including SMTP sender, email group, and email channel. Added LIBID and LIBPATCH versioning to the notifications library and the notifications manager to improve compatibility across charm components. Hardened error handling for invalid object-storage credentials by introducing ObjectStorageConfigValidationError, ensuring the charm is blocked with a clear status and that credential issues are surfaced early. These changes improve alert routing reliability, support smoother upgrades through explicit versioning, and provide clearer feedback to operators during credential problems.

Summary for 2026-01: Expanded cross-cloud backup capabilities and hardened deployment validation in the OpenSearch operator. Key features delivered include Google Cloud Storage (GCS) snapshot support with auto-create bucket behavior across S3, Azure, and GCS, implemented via a new GCS relation endpoint and repository settings to enable consistent backups and restores. Major bugs fixed include Terraform evaluation errors when the optional failover orchestrator is not deployed, achieved by guarding access to failover.model_uuid and stabilizing module outputs. These changes improve backup reliability, reduce manual provisioning, and increase deployment resilience in large-scale, multi-cloud environments. Skills demonstrated span OpenSearch Operator development, multi-cloud storage integration, idempotent resource creation patterns, and Terraform module validation, with testing through manual, unit, and integration tests.

December 2025 performance summary for canonical/opensearch-operator focused on delivering a more resilient, flexible backup/restore workflow and improving operator robustness. Implemented a centralized events-driven snapshot flow, enhanced storage management for backups, and streamlined peer-cluster relation handling. Completed comprehensive testing (manual, unit, integration) and reinforced cloud hygiene.

November 2025: CI Integration Test Workflow Stabilization for canonical/opensearch-operator. Replaced deprecated charmcraft method with spread for job collection, updated workflow to install spread, improving reliability of integration tests in Charmcraft 4.x environments.

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.

Month: 2024-12 1. Key features delivered: - canonical/oai-ran-du-k8s-operator: Extended fiveg_rfsim interface to include network slice information (SST and SD) with robust handling of relation data, enhanced error logging, and expanded test coverage. Commits: ba70453cb3bee5a89ad506a89a3f338ba23ff1a4; e2976b9d30e0405fd07d2cd8f4815d4e210b8040. - canonical/oai-ran-du-k8s-operator: Added a configuration option 'use-three-quarter-sampling' for DU startup with tests updated (commit 00ada6585b7dac01513ab71a3544448045c756be). - canonical/sdcore-nrf-k8s-operator: NRF deployment security via TLS configuration and image update to v1.6.1; adjusted startup/flag handling (commit f365f70dd8e52a3bc2794289d95b0fd826e5c6dc). - canonical/sdcore-amf-k8s-operator: AMF deployment security hardening and version pinning to 1.6.1; TLS enabled and config path clarified (commit 8130126193a23d6e7c74c3fed9a9f61cfbce2b49). 2. Major bugs fixed: - canonical/sdcore-gnbsim-k8s-operator: Fixed simulation success evaluation by counting 'Profile Status: PASS' in gnbsim stdout; improved logging and updated image version (commit ea99c6ba78fd1025ec95f9544830d5cc45e8b37f). 3. Overall impact and accomplishments: - Strengthened security posture with TLS across NRF/AMF deployments, improved reliability via version pinning and robust data handling; expanded device compatibility for DU startup; enhanced observability with improved logs and tests across operators. 4. Technologies and skills demonstrated: - Kubernetes operators, TLS/config management, interface extension, test-driven development, logging instrumentation, image versioning and secure deployment practices.

November 2024 focused on stabilizing SD-Core deployments, modernizing build/run environments, and aligning documentation with the latest tooling. Across all operators, key efforts included: (1) stabilizing gRPC connectivity by upgrading core images and tagging releases (NSSF, NRF, AMF, AUSF, SMF, UDM, UDR), (2) upgrading charm build/run base OS to Ubuntu 24.04 to improve stability and compatibility, (3) aligning docs with current Juju MicroK8s versions and new image tags, (4) hardening security and reliability with TLS support for UDR, and (5) strengthening CI/CD and dependency management by updating base images and charmcraft configurations.

Month 2024-10: Stabilized gRPC connectivity in canonical/sdcore-pcf-k8s-operator by upgrading the sdcore-pcf OCI image from 1.4.3 to 1.5.2, resolving client reconnection issues. The change reduces production downtime and improves service availability for downstream consumers. Implemented via commit 69fb474d3b4769c2efaa134dc8ab6401749038f8 (chore: bump rock image to fix grpc client reconnection issues (#357)).
