About

Data Engineer with 4+ years of experience designing and building scalable data pipelines on Microsoft Azure. I specialize in end-to-end data engineering — from ingestion to transformation to analytics-ready delivery — using Azure Data Factory, Databricks, and Synapse Analytics. I enjoy solving problems around data reliability, performance tuning, and designing pipelines that scale as data volume grows. I'm always looking to deepen my expertise in modern data platform architecture. Currently open to new opportunities where I can apply my Azure data engineering skills to interesting, high-impact problems. Feel free to connect or reach out — always happy to talk data engineering, cloud architecture, or potential opportunities.
