Certified Data Analyst who turns messy datasets into decisive SQL/BigQuery, Python, and Tableau insights for impact.
South AfricaWhat I'm looking for
I’m a certified Data Analyst leveraging SQL (BigQuery), Python, and Tableau to optimize public sector reporting and correct economic narratives. I’m known for translating “messy” datasets into decisive business intelligence for high-impact decision-making.
Recently, I engineered a full-stack data pipeline using BigQuery and Python to analyze Stats SA QLFS data. I automated data cleaning processes, reducing preparation time for complex economic files by 40%, and designed an interactive Tableau dashboard to visualize the growth of South Africa’s middle class.
My background also strengthened my data quality mindset and operational reliability—from conducting tablet-based household surveys to coordinating and overseeing field workers as a Field Worker Supervisor. I’ve also managed administrative workflows as a Personal Assistant and supported election-day logistics through long-term service with the IEC.
