Database Engineer at PDI automating AWS Aurora PostgreSQL operations and monitoring ETL pipelines with AWS Glue.
IndiaWhat I'm looking for
At PDI, I automate database operations across AWS Aurora PostgreSQL, PostgreSQL, SQL Server, MySQL, and Redshift. I also built and maintain AWS Glue ETL monitoring to catch pipeline failures and data issues.
I’m the sole database owner for a loyalty-program-critical system, managing its performance, availability, and data integrity without a dedicated team. I replaced recurring administrative tasks with scripted, repeatable automation.
At KGiSL Technologies, I led database administration for financial services, banking, and government clients. I designed high-availability and disaster-recovery strategies, supported database migrations and upgrades, and implemented security controls including TDE, HIPAA, PCI, and PII requirements.
