Skills in practice
A closer look at the architecture, integrations, and quality controls behind my project work—including an implemented AI-to-CMS automation workflow in Nova.
Explore all skillsImplemented in Nova
I designed and implemented an AI-assisted workflow where Hermes Agent researches and discovers content, returns structured JSON, and hands control to a TypeScript application pipeline. The application validates, filters, deduplicates, ranks, and transforms candidates before creating draft-only entries in Directus for human editorial review.
Feature boundaries, shared data layers, reusable administration patterns, and maintainable project structure across large product surfaces.
