About

Data Engineering professional with 14 years of experience, specializing in building enterprise-scale data platforms and serving as a Data SME across cloud, analytics, and engineering initiatives. Over the last 5 years, I have focused on modern data engineering, developing scalable pipelines and Delta Lake architectures on Databricks using Apache Spark, Python, and AWS services to deliver reliable, high-quality data for regulatory reporting, dashboards, and AI/ML workloads. I bring deep expertise in ETL/ELT design, data modeling, Lakehouse architecture, performance optimization, and large-scale ingestion frameworks. My experience includes end-to-end pipeline development, automation using Terraform and Jenkins, and observability through Splunk to ensure robust, production-ready systems. I also lead engineering teams, mentor developers, and drive delivery excellence while shaping data strategy, standards, and best practices across the platform.
