Data Engineer at Aspire Systems building Databricks Lakehouse pipelines that transform data from multiple sources into curated analytics datasets.

India

Message

At Aspire Systems, I design and implement data models and pipelines within a Databricks Lakehouse architecture, integrating data from multiple source systems into curated datasets for analytics.

I also develop ingestion pipelines for Bronze-layer data and use PySpark for transformations and aggregations across Silver and Gold layers. My work includes Delta Tables, Auto Loader, and Databricks Jobs.

Earlier at Aspire Systems, I developed an event-driven pipeline that routed source-data changes through AWS EventBridge and Lambda into Apache Iceberg tables. I also used Python, Pandas, and AWS services to process incoming event payloads.

My previous work includes building Azure Data Factory pipelines at Speridian Technologies and developing Oracle PL/SQL ETL pipelines, data transformations, and database objects at Cognizant Technology Solutions.
