What I'm looking for

I'm looking for BI and analytics engineering work where I can own or strengthen the full data lifecycle, build trusted dashboards and pipelines, and help stakeholders make evidence-based decisions across flexible remote collaboration.

I've delivered end-to-end BI solutions for Ozyn Tech, IQVIA, and the City of Johannesburg, spanning data ingestion, dimensional modelling, automated pipelines, and executive Power BI dashboards. My work has surfaced a 30% outperformance against patient waiting-time targets and identified R180,000 in annual advertising overspend.

With 9+ years across pharmaceutical market intelligence, public-sector geo-analytics, healthcare, e-commerce, and retail, I build reliable reporting foundations using Power BI, SQL, ETL/ELT, Azure Data Factory, GA4, and BigQuery. I enjoy owning the full BI lifecycle while making complex data clear and actionable for executive and non-technical stakeholders.
