About

NOTE: Open for New Roles. I’m a Data Engineer with 7+ years of experience architecting and scaling cloud-native data pipelines that power high-growth products and real-time decision-making. I bring deep expertise in ETL development, data modeling, and automation, with a track record of delivering solutions from raw ingestion to insight. Proficient in SQL, Python, Snowflake, and PySpark, I build resilient data architectures using Azure Data Factory, Databricks, and orchestration tools like Apache Airflow. I’ve also collaborated with ML teams to productionize models using MLOps best practices, ensuring performance, reproducibility, and monitoring at scale. Currently exploring the integration of Generative AI (Llama-2) to enhance data cleaning, accelerate transformation, and derive deeper insights from unstructured data—merging classical data engineering with AI innovation.
