Designing GDPR-, UK Online Safety Act-, and DSA‑Compliant Serverless REST Endpoints for AI‑Powered Career Assistants

As a product leader who has shipped AI‑driven career tools at scale, I focus on turning regulatory constraints into architectural guardrails. The following pattern shows how to expose a skill‑gap inspection endpoint that is fully serverless, observable, and compliant with the three major EU/UK frameworks that affect creator‑economy platforms in 2026.
