At Kaizen IT Services, I design and maintain Azure Data Factory and Azure Databricks pipelines that collect, process, and store large datasets from on-premises and cloud sources in Azure Data Lake Storage.

I build Bronze, Silver, and Gold data models with Python, PySpark, and SQL, creating analytics-ready datasets for reporting. I also apply validation and reconciliation checks, tune pipeline performance through partitioning, file sizing, caching, and join strategies, and troubleshoot production issues.

Previously at Tech Savvy Software and Security Consultancy, I developed Python and PySpark ETL jobs in Azure Databricks and built reliable Azure Data Factory ingestion pipelines. I work closely with analysts and data scientists to turn requirements into documented Azure data solutions, supported by Git, code reviews, CI/CD, and Agile delivery.
