01
Work
Public projects. The short descriptions come from each repository, not from a press kit.
algorithms-visualization
Step-through animations for 92 data structures and algorithms. Seventy-seven algorithm pages replay one step at a time, with TypeScript, Python, Go, and Rust highlighted on the same line.
llm-sanguo
A static page that seats large language models as Romance of the Three Kingdoms XIV officers, using an Artificial Analysis snapshot and a published weighting method.
- L0Resident rules and the routing table. Loaded every session, and kept short.
- L1One spec for the kind of work, read before starting.
- L2The module or change: a plan with status and a replacement link.
- L3Evidence. Reports and audits, never the entry point.
agent-doc-architecture
Documentation treated as a routing system for large projects whose first reader is an AI agent. The repository includes the L0–L3 model and an agent-first-docs skill you can copy into another project.
skyfire-1943
An original air-combat prototype in three views: side-scrolling, top-down, and a pseudo-3D chase. The name nods to 1943, Salamander, and Sky Destroyer. It does not use their ROMs, artwork, or music. Playable research build.
Smaller projects
Also
LumiDeck
An AI slide studio: start a deck and edit it in conversation. The public repository is named big-ppt. The live workspace asks you to sign in.
IllegalCreed Quiz
A Vue, NestJS, and MySQL quiz application for practicing developer questions by topic. Public repository: Quiz-monorepo.
ai-network-guard
A macOS menu-bar tool that checks the network exit seen by Claude Code, ChatGPT, and other overseas AI agents, and notifies you when that exit looks inconsistent.
content-studio
A local-first toolkit for producing articles, images, and video across projects, with an agent plugin and a Vue workbench. Channel credentials stay outside this repository.
marketing-ops
Local, credential-isolated campaign publishing and feedback collection. Platform secrets stay in the macOS Keychain; the agent sees project policy, not credentials.
Programmer roadmap
A maintained knowledge base, separate from this site: notes from web foundations through frontend, backend, databases, systems, security, DevOps, and architecture.

Writing
Agent-first Docs
dev.to (opens in a new tab)A four-part series on dev.to about documentation for large projects in the agent era.
- Agents Aren’t Amnesiac — They Can’t Find the Entry Point (opens in a new tab)
Why an agent seems to forget: it cannot find the entry. A four-layer (L0–L3) model.
- Make the Agent Read Only What It Should (opens in a new tab)
Routing, so a task loads the one document it needs.
- Give Every Document Exactly One Place (opens in a new tab)
Addressing rules, so each document has a single authoritative home.
- Keep Documents from Rotting (opens in a new tab)
A lifecycle for creation, health checks, and archiving.
Essay
See Quick Sort partitioning, one step at a time (opens in a new tab)Quick Sort is easy to summarize: choose a pivot, partition, and repeat. Following one partition is harder. A short walk through the visualizer.
