What I'm looking for

I'm looking to lead and deliver mission-critical database architecture, cloud migration, high availability, performance tuning, and automation initiatives across Oracle, PostgreSQL, Cassandra, AWS, and OCI.

I've supported mission-critical database environments for NuvemLab, Persistent Systems, TCS, Orange Business Services, NIIT Technologies, and Wipro. I manage Oracle RAC, Data Guard, ASM, PostgreSQL, Cassandra, MariaDB, and AWS RDS production systems.

I’ve migrated SQL and NoSQL databases to AWS, OCI, and Tencent Cloud, including Oracle-to-PostgreSQL migrations using SCT. I designed data models for high-traffic OLTP and data warehouse environments handling more than 2 million daily transactions, reducing query latency by over 40% through physical and logical model optimization.

I work hands-on across backup and recovery, replication, performance tuning, disaster recovery, monitoring, and automation. My work includes AWR, ASH, ADDM, CloudWatch, OEM, pgAdmin, pgBadger, Shell scripting, Ansible, and Terraform.

I enjoy working with developers, DevOps, security teams, and business analysts to deliver stable, scalable, compliant database platforms in 24x7 production environments.
