What I'm looking for

I'm looking to build reliable data pipelines, dashboards, and analytical solutions that help teams make better operational and business decisions.

I've built data pipelines, KPI frameworks, and dashboards that turn operational data into business decisions. My work spans SQL, Python, ETL, Spark, Snowflake, Tableau, and Power BI.

At RR Donnelley, I built SQL-based ETL pipelines across revenue, cost, and operational data, reducing manual effort by 40%. I also supported Spark-based ingestion integrations that reduced analytics turnaround time by 30% and created KPI dashboards for global clients.

Previously at Ericsson India Global Services, I consolidated multi-source network data with SQL and Python, monitored 10+ network KPIs, and investigated reporting bottlenecks. More recently, I've built an Airflow and Snowflake tennis data warehouse, analyzed 31M+ flight records with PySpark, and deployed AI-driven workflows on AWS.
