For a single-engineer Angular engagement the math runs different from a multi-developer enterprise frontend pod. One Angular dev for a 4-month RxJS modernization = 640 hours at $80/hr ≈ $51,200. Compare against a Big Four IT consulting engagement ($180k–$250k for the same scope) or a US in-house hire ($195k/yr loaded plus a $25k ramp). Single-dev wins for one-app modernization scope under 18 months — once the work spans 3+ Angular apps or requires concurrent Material upgrade + NgRx restructure + signals migration, a 3-engineer enterprise pod becomes the right tier.
