Experience
Data Engineer
Nov 2024 — Present · Gurugram, IN
As a Data Engineer, I designed and deployed scalable ETL pipelines that powered core analytics use cases including App Transactions tracking, User Locations, and Application Source Insights. From schema modeling to iterative logic refinement, I focused on optimizing performance and reducing storage and compute costs, significantly improving data accessibility for dashboards and reporting. I built and maintained high-performance BigQuery tables by transforming raw application data into structured formats using PySpark, Apache Airflow, and GCP native tools enabling reliable insights delivery across internal teams and external clients.To support business intelligence efforts, I led proof-of-concept studies focused on data aggregation and processing efficiency, surfacing actionable insights such as user transactions applications usage behavior and app lifecycle trends. I played a key role in strengthening pipeline reliability by resolving critical workflow failures, automating monitoring systems, and enhancing alerting to maintain uninterrupted data flow. Additionally, I led the consolidation of fragmented datasets across Bobble and Mint keyboard platforms, simplifying data access and improving query performance. Earlier, I also initiated a cloud cost optimization project that reduced GCP storage expenses by 20% through in-depth audits.Technologies: Python, PySpark, SQL, Apache Airflow, BigQuery, GCP (Cloud Storage, DataProc, etc)
