At Tata Consultancy Services, I build real-time data engineering solutions for JetBlue on Microsoft Fabric. I migrated legacy Cosmos DB and Snowflake workloads into an event-driven Medallion architecture while preserving data integrity and minimizing downstream disruption.

I engineered Lakehouse pipelines handling a 10M+ historical load and 100K+ daily real-time events at a 99.9% success rate. I also built Silver-layer XML-to-JSON transformations, deduplication, CDC logic, and delta-only publishing for downstream consumers.

I designed a Gold reservation table that powers five production REST APIs for booking, flight, loyalty, email, and phone lookups, delivering sub-200ms response times against a 400ms SLA. I also built Eventhouse, Eventstream, Event Hub, Fabric Activator, and real-time dashboard workflows for low-latency consumption and proactive pipeline monitoring.

Previously, at Genius Consultants supporting Ericsson, I developed a Python KPI report automation bot that cut manual effort by 80% and reduced daily reporting by more than three hours. I bring hands-on experience across Microsoft Fabric, Azure Databricks, PySpark, Delta Lake, streaming, and data warehousing.
