GCP Database & Logging Cost Optimisation
2026
A production cost-control initiative using monthly Cloud SQL PostgreSQL partitions, historical-data archival, partition-based retention, and focused Cloud Logging to constrain recurring storage and logging cost growth.
Key Achievements
- Controlled active Cloud SQL storage growth through monthly partitioning, archival, and partition-based retention
- Improved recent time-series query paths by allowing PostgreSQL to prune irrelevant historical partitions
- Replaced large row-by-row retention deletes with fast removal of expired partitions

Key Achievements
- Standardised development, staging, and production delivery around versioned artifacts from a shared Artifact Registry
- Created reusable Kubernetes configuration with common Kustomize bases and service- and environment-specific overlays
- Implemented keyless GitHub Actions authentication to GCP through Workload Identity Federation
