Gundupalli Naveen

I’m a Database & Cloud Developer and Database Migration Specialist with 6+ years of experience designing, developing, and optimizing applications. I focus on Oracle SQL, PL/SQL, PostgreSQL, and Python to support critical business operations with reliable, efficient database solutions.

My work centers on building and tuning data-intensive systems—developing Packages, Procedures, Functions, and Triggers, and applying advanced PL/SQL techniques like bulk collections, cursor management, and exception handling. I also optimize execution time using SQL and PL/SQL performance tuning and execution plan analysis.

In cloud-native environments, I build and automate using AWS services such as AWS Lambda, Amazon S3, Amazon RDS, and CloudWatch. I’ve implemented cron-style automation for scheduling SQL queries, report generation, and file transfers, and I manage and monitor PostgreSQL environments for operational stability.

I’m especially strong in database migration with minimal downtime—migrating schemas, tables, views, and procedural logic from Microsoft SQL Server (T-SQL) and Oracle to PostgreSQL (PL/pgSQL). I validate migrations through data reconciliation, reconciliation scripts, performance testing, and issue resolution to ensure smooth application functionality.
