What I'm looking for

I seek senior DBA roles focused on PostgreSQL and cloud migrations (Azure), with emphasis on HA/DR, automation, performance tuning, and cross-team collaboration to deliver resilient, scalable database platforms.

I am a Senior Database Administrator with 14+ years of multi-database experience across PostgreSQL, MySQL, MSSQL, MongoDB, Oracle, SAP HANA, and IBM DB2, focused on delivering resilient, secure, high-performing database solutions for banking, telecom, fintech, and enterprise clients. I lead end-to-end on-prem to Azure migrations, design HA/DR and clustering strategies, and automate DBA tasks with Terraform and Python to ensure minimal downtime and strong operational governance.

I have driven large-scale migrations and performance optimizations—migrating a 4 TB PostgreSQL database to Azure with zero data loss, implementing Patroni-based high availability, and cutting query times up to 60% via vacuum tuning and index redesign. I collaborate with infrastructure and application teams, produce capacity and performance reports, and run disaster recovery simulations to meet strict RTO/RPO targets.
