Senior Data Engineer improving enterprise ETL/ELT pipelines with Python, SQL, and cloud data platforms across Azure, GCP, and Databricks.
ZimbabweWhat I'm looking for
I’m a Senior Data Engineer focused on designing, building, and optimizing large-scale ETL/ELT pipelines and cloud data platforms. I’ve architected production-grade data infrastructure that powers enterprise analytics and reporting while improving performance and reducing infrastructure costs.
At Procter & Gamble, I own and architect a centralized commercial ETL platform, administer Databricks dev/prod environments, and implement compute optimization to strengthen governance and security. I engineered high-volume media pipelines in GCP processing 1B+ records using Cloud Composer/Apache Airflow, eliminating 20+ hours per week of manual reporting effort.
Previously, I built an end-to-end commercial ETL pipeline and executive reporting dashboard, scaling to 60+ users and 2,000+ monthly views. I introduced automated testing and data validation with Git version control, reducing pipeline runtime by 50% and improving data reliability, while also delivering $1M in annual cost savings through API-driven media pipelines.
