What I'm looking for

I'm seeking Principal Data Engineer or ETL Consultant roles focused on scalable data ingestion, PySpark/Spark SQL transformation, ODI-based integration, enterprise data warehousing, and building Agentic Platforms.

At Oracle India Pvt Ltd, I build and support the enterprise data platform behind Sales Intelligence, turning data from multiple source systems into curated, reporting-ready datasets. I use PySpark, Spark SQL, Python and SQL to develop ingestion and transformation pipelines.

For the Sales Intelligence platform, I engineered a natural language-to-SQL interface with Oracle Database 26ai Select AI, DBMS_CLOUD_AI and OCI Generative AI. It translates business questions into enterprise SQL queries for self-service analytics, with data-governance guardrails.

At Sopra Steria, I developed integrations for telecom data including equipment, orders, sites and addresses, and designed reusable processing components from business rules. I also integrated Oracle Database and PostgreSQL with REST APIs and XML interfaces.

Earlier, at Wipro InfoTech, I developed ODI flows for Vodafone Turkey and Bharti Airtel data warehouses, including feeder-file ingestion, reconciliations and Exadata loads. I hold Oracle Cloud Infrastructure Foundations 2020 Associate and Oracle Autonomous Database Cloud 2019 Specialist certifications.
