Welcome to Cường Nghiêm

Welcome to Cường Nghiêm — the public surface of a private second brain built in Obsidian.

This is not just a typical blog. Behind the site is a layered system designed to accumulate knowledge over time:

• raw sources stored privately in the vault
• a living wiki maintained and expanded by an LLM
• project context for active work
• a selective publishing layer that exposes only what is worth sharing

Visual summary: core structure behind the article argument.

The goal is simple:

• do not let useful thinking die inside chat history
• do not turn every private note into public content
• do not rediscover context from scratch every time like plain RAG workflows
• let knowledge compound into a maintained wiki over time

From here on, the best parts of that system will be published under the Cường Nghiêm name:

• blog posts
• research notes
• evergreen docs
• long-form syntheses worth keeping

The private layer remains private. That is where the raw material lives, where ideas are linked, and where the deeper work continues.

This is only the beginning. Future writing here will go deeper into topics like:

• what an LLM wiki actually is
• how to use Obsidian as a true second brain
• how to separate private knowledge from public publishing
• how to move from source → wiki → polished article

Welcome to the public edge of a system that is still growing.
