Alexandra Nac (Alex) is a full-stack developer focused on applied AI, RAG systems, agentic workflows, CMS architecture, UI/UX thinking, and automation. This site is her personal knowledge hub — work, field notes, custom tools, and experiments from building real systems.
She works across applied AI and the platforms it runs on: retrieval and RAG pipelines, evaluation and cost tracing for language models, dynamic CMS architecture, and the interfaces on top. This site is itself the working example — the content model, the reasoning layer that answers questions about it, and the design-token system that styles it were all built and are all documented here. She also builds with AI assistance openly rather than quietly: the architecture calls, the standard, and what ships are hers.
