Alfredo Flores Valenzuela — Systems for Real Businesses

Field notes

The portfolio documents software at the level of shifts, treatment rooms, payment methods, product modifiers, and business-day cutoffs. One venue system separates totals by cashier shift and reconciles cash against card payments, while the CRM models account credit as traceable movements. The site also records a concrete production failure: an undocumented 1,000-row API limit silently truncated monthly reporting until aggregation was moved server-side and four months of figures were back-filled.
