About Me & Interactive CV

Data engineering roots. An obsession with AI automation.

I'm Sandile D. Mfazi, a Business Intelligence Consultant based in Gaborone, Botswana, and a First-Class Honours graduate in Business Intelligence & Data Analytics (1:1 with all six distinctions).

By day, I engineer enterprise data warehouses, automated ETL pipelines, and semantic models across Botswana, South Africa, and Zambia—handling 1.7B+ records across the Microsoft Data Stack. Outside of enterprise BI, I'm building practical Business AI Automation workflows and preparing to launch a YouTube channel sharing AI systems, tech tutorials, and personal reflections.

Why This Personal Hub Exists

I used to position this site purely as an independent B2B consultancy storefront. Now, I'm turning it into my personal home on the internet—where my engineering portfolio, AI automation writing, upcoming YouTube channel, and career journey live side by side.
