Hi, I'm Ilayaraja Ravi
Data Engineer | Azure Databricks | PySpark | Python | SQL | Full Stack
I build scalable data pipelines and modern data platforms using Azure Databricks, PySpark, Delta Lake, Azure Data Factory, and Python.
With over 8 years of experience in software development, including data engineering, I enjoy transforming raw data into reliable, high-quality datasets that power analytics and business decisions.
I am currently focused on designing end-to-end Azure data engineering solutions using the Medallion Architecture, Delta Lake, and cloud-native data services. I also share my learning journey through technical blogs and hands-on projects.
Open to Data Engineer opportunities.
