Usually yes. A senior full-stack engineer can take most MVPs from schema to deployment alone. Add specialists once the product proves itself and one layer becomes the bottleneck.
Hourly rates are comparable, but total cost is often lower because one person covers work that would otherwise need two coordinated specialists.
Depth on your critical layer, not equal depth everywhere. A truly balanced profile is rare; make sure the strong side matches where your product's risk lives.
