Data Engineer at CPM India Sales & Marketing Pvt. Ltd. who built a config-driven SQL Server-to-ClickHouse pipeline with Parquet backups.

At CPM India Sales & Marketing Pvt. Ltd., I built a config-driven Python ELT pipeline moving SQL Server data to ClickHouse, with Parquet backups. I also built dlt/dbt Bronze, Silver, and Gold models for analytics and Superset reporting.

As a freelance Data Engineer, I developed PySpark transformations on Databricks for Lokayat LLP and scheduled pipelines with Airflow. Earlier, at Mangla Apparels India Pvt. Ltd., I maintained PySpark pipelines processing 10M+ rows daily and helped cut query latency by 40% with event_date-based partitioning.
