Olaniyi Olafusi EmmanuelBuilding resilient PostgreSQL and cloud-native data platforms.

• Designed and managed high-availability PostgreSQL clusters across dev, QA, staging, and production, supporting 1M+ monthly transactions.
• Led PostgreSQL version upgrades with zero data loss, carefully planning replication, backups, and rollback strategies.
• Implemented CI/CD pipelines with GitLab and Jenkins for database changes, accelerating deployments by 35% while minimizing downtime.
• Built and tested backup/restore pipelines, achieving a recovery point objective under 15 minutes.
• Implemented MongoDB replica sets and sharded clusters, enabling 50% higher data loads with improved fault tolerance.
• Automated cluster scaling on Kubernetes, cutting downtime by 40% and saving 15+ engineer hours per month.

Project work focused on running PostgreSQL on Kubernetes and cloud infrastructure using Terraform, Git, and container best practices.

• Deployed PostgreSQL on Kubernetes and VMs, achieving 99.9% uptime across staging and production environments.
• Automated cloud resource provisioning with Terraform, reducing infrastructure rollout from days to under two hours.
• Created and managed Kubernetes namespaces and roles to enforce fine-grained access control and security policies.
• Tuned Terraform modules and Kubernetes manifests for scalable, secure, and efficient PostgreSQL deployments.
• Conducted disaster recovery drills and ensured data integrity with robust backup and recovery strategies.
• Applied container and network security best practices, including network policies and security contexts.
• Collaborated with cross-functional teams to optimize performance and document best practices for operating PostgreSQL in the cloud.
