Manage deployments, environment variables, webhook integrations, and staging environments
Maintain third‑party integrations including Pardot, GTM, GA4, Hotjar, Drift, and review widgets
Design and build agentic workflows where AI handles structured, repeatable tasks such as content extraction, transformation, QA comparison, and draft generation
Use the Sanity MCP server and Claude API in production workflows, not just for one‑off prompts
Build Vision QA pipelines (Playwright + Claude screenshot comparison) and other automated validation steps
Contribute to the AI co‑authoring layer that enables Marketing to publish content with AI assistance and Dev oversight
Work with Marketing to define content ownership, review workflows, and editing guardrails in Sanity Studio
