I am an experienced analyst programmer and data professional with over four years building ETL pipelines, dashboards, and data solutions that drive business insights. I combine hands-on development in Python and SQL with BI tool expertise to translate raw data into actionable reporting.

At OK Zimbabwe I designed SSIS and AWS-based ETL processes, migrated databases to cloud storage, and built KPI dashboards that reduced decision latency by 30%. I have driven performance improvements, including a 45% query performance gain and 99.8% data accuracy for financial reports through automated checks.

My technical approach emphasizes scalable architectures and cost efficiency — I optimized AWS Glue workflows to reduce pipeline costs by 22% and have been expanding skills in AWS data services and Redshift to support enterprise reporting. I also prioritize team enablement, having trained 15+ colleagues on BI tools and coordinated CI/CD deployments.

I am currently developing a VB.NET/MS SQL inventory application to formalize desktop development experience while continuing to deliver cloud-integrated analytics solutions that enhance decision-making and operational performance.
