This path builds on the core developer skills to tackle production-grade SaaS CMS work. You'll master advanced content modeling with contracts and base-type immutability, then level up your Optimizely Graph skills with semantic search, cursor pagination, boosting, and complex query patterns. You'll tune Graph performance through indexing, caching, and query diagnostics, and handle advanced REST operations. You'll federate external content into Graph, wire up variations and experimentation, automate with webhooks and environment promotion, and harden for production with observability, MCP, and Opal tooling. By the end, you'll run SaaS CMS at scale.
