Problem. A food venture needed to model COGS, margins, labor, kitchen cost, and cash flow across SKUs — and stress-test it.
What I built. A from-scratch reactive engine in vanilla JS: 5 SKUs with a live COGS builder (ingredient cost × quantity), margin/labor/cash projections, red-team worst-case scenarios, and a global-inputs settings tab. Nothing hardcoded — every output is a live formula. Mobile-first, 44px touch targets per Apple HIG.
Why it matters. Complex interconnected state without a framework, plus genuine business/unit-economics fluency — useful when an applied engineer has to reason about customer ROI on the spot.
