Olaniyi Emmanuel Olafusi

I’m a Database Engineer with 3+ years’ experience managing and optimizing mission-critical systems across PostgreSQL, MySQL, and DB2. I’ve focused on improving query performance and reliability, delivering 99.9% uptime while handling 1M+ monthly transactions.

In my Audipsalm IT Solutions role, I managed high-availability PostgreSQL clusters across development, QA, staging, and production. I led PostgreSQL version upgrades with zero data loss, implemented automated failover with <15-minute RPO, and reduced average query response times by 30%, improving API throughput for 5+ production systems.

I also strengthened the platform through automation and infrastructure work. I deployed PostgreSQL on Kubernetes/VMs, automated provisioning with Terraform and Ansible using Python, and supported database migrations across environments using AWS DMS and Azure Data Factory for zero data loss with minimal downtime.

My approach is rooted in observability and incident readiness. I built real-time monitoring dashboards in Datadog and SolarWind, reducing MTTR by 40%, authored internal runbooks and DBA procedure documentation, and supported disaster recovery with backup/restore pipelines. Now, I’m pivoting into Technical Support Engineering, leveraging my incident diagnosis and clear technical communication for customer-facing success.
