20 years in Enterprise IT. One month with Claude Code. Never going back.

I'm not a software engineer. I haven't solved a LeetCode problem in my life. For nearly two decades, I ran IT infrastructure at companies where "writing code" meant updating a spreadsheet macro.

Then AI happened.

Taiwan (1985-) -- Studied CS at National Central University. Spent more time running the campus network, co-building a MUD (still running after 20+ years), and managing the highest-traffic personal BBS board than writing code.

US (2008-) -- Master's in CIS. Then nearly 20 years of enterprise IT:

One year, I wrote maybe one line of code. Never touched GitHub.

Now -- Downloaded Claude Code. Built an AI agent framework in weeks. Shipped more in a month than most side projects ship in a year.

I design from an IT veteran's perspective -- not "how do I write the cleverest code," but "what actually works for people who aren't engineers."

A web app that orchestrates ChatGPT, Claude, Gemini, and Grok from a single input -- open to everyone, running on my own paid API keys. Parallel chat, structured debate, an 8-step coding loop, a multi-round roundtable, plus single-AI agent modes. Tiered plans with quota + subscription billing, per-tier model routing, SSE streaming. Hono + SQLite + React on Oracle Cloud ARM behind Caddy. Grew out of my multi-ai-chat Chrome extension.

A security hardening layer for AI agent hosts. A chattr +i policy baseline no agent can rewrite, a guardian subagent, and a deterministic cross-patrol heartbeat / dead-man's-switch -- bolted onto OpenClaw without touching its code. Apache-2.0.

Claude Code skills wrapper. Lightest weight, curated features, maximum performance. One generator command, you're running. 25 MB RAM, 672 KB on disk.

Unified long-term memory for AI agents. SQLite + Oracle + Vector Search.

A hands-on study of IDN homograph attacks -- the "looks legit, isn't" threat I spent years defending against.

This isn't code written by a 20-year software engineer. It's the best path found by a 20-year IT / MIS / Cybersecurity veteran who knows what enterprises actually need.

The best developer tools come from people who've spent decades as users of technology. I know what breaks at 3 AM, what IT teams actually adopt vs. what dies after the demo, and why "just works" beats "highly configurable" every time.

Building a multi-AI agent fleet -- Claude, GPT, Gemini, and local models working as a team with defined roles, real accountability, and honest performance scoring. Not a demo. Running in production, every day.

20 年企業 IT。一個月 Claude Code。回不去了。

我不是軟體工程師。這輩子沒解過一題 LeetCode。將近二十年，我在企業裡管 IT 基礎建設，「寫程式」對我來說就是改 Excel 巨集。

然後 AI 來了。

台灣（1985-） -- 中央大學資工系。比起寫程式，更多時間在管校園網路、共同開發 MUD（營運至今 20+ 年），以及經營全校最高人氣 BBS 個版。

美國（2008-） -- CIS 碩士。接著近 20 年企業 IT：

一整年，我大概寫了一行 code。從沒碰過 GitHub。

現在 -- 下載 Claude Code。幾週內打造一套 AI Agent 框架。一個月的產出超過多數 side project 一年的進度。

我用 IT 老兵的視角 設計工具 -- 不是「怎麼寫最聰明的 code」，而是「什麼東西非工程師也能用」。

一個 web app，一個輸入同時調度 ChatGPT、Claude、Gemini、Grok -- 開放給所有人用，跑在我自己付費的 API 上。平行對話、結構化辯論、8 步 coding loop、多輪圓桌論證，外加單一 AI 的 agent 模式。分級方案（額度 + 訂閱計費）、各級模型路由、SSE 串流。Hono + SQLite + React，部署在 Oracle Cloud ARM、前掛 Caddy。源自我的 multi-ai-chat Chrome 擴充。

AI agent 主機的安全強化層。任何 agent 都改不掉的 chattr +i 政策基線、守護 subagent，以及確定性的 cross-patrol heartbeat / dead-man's-switch -- 直接加掛在 OpenClaw 上，完全不動它的程式碼。Apache-2.0。

Claude Code skills wrapper。最輕量、精選功能、極致效能。一條指令，直接跑。25 MB RAM，672 KB 磁碟。

AI Agent 統一長期記憶。SQLite + Oracle + Vector Search。

IDN homograph 攻擊的實作研究 -- 那種「看起來合法、其實不是」的威脅，正是我防守多年的東西。

這不是一個 20 年軟體工程師寫的程式。這是一個 20 年 IT / MIS / 資安老兵找到的最佳路徑。

最好的開發者工具，來自於花了數十年當技術 使用者 的人。我知道什麼東西凌晨三點會壞、IT 團隊真正會採用什麼 vs. demo 完就丟的東西，以及為什麼「就是能用」永遠打贏「超級可設定」。

打造多 AI Agent 艦隊 -- Claude、GPT、Gemini、本地模型作為一個團隊運作，有明確角色、真實問責、誠實績效評分。不是 demo，每天都在 production 跑。
