Data Engineer II

NextSCM Solutions Pvt. Ltd (Increff)

Nov 2025 - Present

Spearheaded Data Warehouse migration from Azure SQL DB to ClickHouse, scaling capacity to ingest and manage over 1 billion records; implemented Star Schema data modeling to improve query performance and reduce cloud infrastructure costs by 30%. Engineered an automated post-transformation data validation script that proactively identifies data mismatch root causes (lake vs. warehouse level), serving as the primary diagnostic tool for the client management team and reducing escalations. Built an AI application using CrewAI that translates natural language into SQL, automating the generation of data insights and visualizations and empowering non-technical users to self-serve complex data queries. Contributed to the Apache Superset open-source community by implementing role-based access control (RBAC) to enable dashboard duplication without requiring owner-level access.
