Data Engineer at Expeditus building Microsoft Fabric ETL pipelines and auditable sales reconciliations for SEAL Retail Solutions.

South Africa

Message

At Expeditus, I build Microsoft Fabric ETL pipelines and sales reconciliation solutions for SEAL Retail Solutions. I developed a dynamic SQL framework that compares source-file row counts with warehouse fact tables, giving the client auditable proof that each load is complete.

I also build Power BI and Excel dashboards, troubleshoot production pipeline failures, and write Python automation for lakehouse file handling and billing workflows. I use AI-assisted development and analysis, validating outputs before release.

For Bidfood and SBV, I resolve managed-services tickets and support KPI reporting and reconciliations. Earlier, I provided remote client services for UK businesses and built websites with HTML5, CSS, JavaScript, PHP, and SQL; I also hold the Microsoft Certified: Power BI Data Analyst Associate (PL-300) certification.
