Sean Steyn (SigmaDev11)
Cape Town-based coffee data wrangler by day, code enthusiast by night. After 20 years keeping the hospitality world caffeinated, I'm now the guy analyzing stock movements across 250+ Vida e Caffè shops while teaching myself to speak fluent Python and SQL. Fascinated by how AI is democratizing development and making it possible for curious minds to build cool stuff without a CS degree. When I'm not elbow-deep in spreadsheets or debugging my latest project, you'll find me exploring ancient wisdom, quantum mechanics, or figuring out how to automate yet another mundane task. Currently tinkering with: Database optimization • Data viz • AI-powered workflows • Making Excel do things it probably shouldn't
