ABOUT OZZIE A.
I build data pipelines with Azure Data Factory, Databricks, Synapse, and SQL. The pipelines pull live IoT data, store it in Delta Lake, and feed Power BI dashboards used by operations, finance, and leadership. Recent results - Cut ETL time by 80 percent - Reduced Databricks costs by 35 percent by fixing the small‑file issue - Helped a trucking fleet reach 99 percent on‑time delivery with real‑time data Now I am scaling lakehouse setups, speeding up PySpark jobs, and guiding teams on CI/CD in Azure DevOps.
