• Collaborate cross functionally. Work side‑by‑side with Product, Backend, and Frontend teams; clarify requirements, hand off specs, review builds.
• Leverage AI wisely. Use AI design/copy tools to accelerate work, but validate everything -you own the outcome.
• Document everything. Keep flows, components, and rationale well documented for the distributed team.
