  • · Hidden offshoring with no named technical lead and no time-zone overlap
  • · No SLA on bug fixes, no documented post-launch support terms
  • · Can't talk fluently about Core Web Vitals, Lighthouse, or WCAG 2.1 AA accessibility
  • · Suspiciously low fixed-price quotes that skip discovery and assume zero scope creep
