@tobilobajoel
Data Engineer building Python and Spark pipelines for reliable, analytics-ready datasets.
What I'm looking for
In my independent data engineering projects, I’ve built end-to-end ETL pipelines with Python, Pandas, and SQL to move structured and semi-structured data into PostgreSQL and BigQuery. I’ve also developed PySpark jobs, tuning performance through partitioning strategies and reduced unnecessary shuffles.
I’ve added data quality checks for missing values, duplicates, schema drift, and anomalies, and orchestrated scheduled workflows with Apache Airflow. I document pipeline architecture and data lineage, and have explored AWS data services while using Docker for consistent local development.
