Data engineer building AWS and Python ETL pipelines, including an automated Premier League data pipeline.

Ghana

Message

I engineered a production-grade English Premier League data pipeline using AWS and Python, automating data ingestion through REST APIs and replacing fragile web-scraping methods.

The project stores raw JSON and curated CSV data in an Amazon S3 Medallion Data Lake. I added daily GitHub Actions workflows, Amazon SNS notifications, and Docker containerization.

At Ghana Broadcasting Corporation, I designed data pipelines for viewer insights and created Power BI and Tableau dashboards tracking ratings, social media interactions, and ad performance.

Across broadcasting, energy, and defense work, I've contributed to cloud security, technical documentation, data analysis, and IT systems. I'm an AWS Certified Cloud Practitioner and am available for relocation and remote work.
