US metro senior engineers $120–$220+/hr through agencies; nearshore LATAM $45–$90; established offshore centers $25–$60 — equivalent seniority, 30–50% total savings realistic with the right partner.
Junior ($15–$50 offshore-to-US) executes specified tasks; mid ($30–$100) owns features; senior ($50–$150+) owns systems and unknowns — title inflation is rampant, so interview for the definition, not the label.
AI/ML and specialized platform skills carry 15–40% premiums; mainstream web stacks price at baseline; scarcity, not difficulty, sets the delta.
The cheap engineer who needs rework is expensive; the senior who prevents the rewrite is cheap — evaluate on delivered outcome economics, which is the only rate that matters.
Skipping the discipline this article describes until an incident, audit, or stalled project forces it — every practice above is cheaper adopted early than retrofitted under pressure.
