Welcome. This is where I write about what I build and learn — mostly
engineering, DevOps, and self-hosting, with some AI automation and Web3
experiments mixed in.

## What to expect

English is the primary language here. I'll write selectively in Chinese
(简体中文) for topics where a Chinese-speaking audience is better served —
those posts will live under `/posts/zh/`.

Most posts will be one of a few shapes:

- **Case studies** — "how I built X", with the architecture and the mistakes.
- **Tutorials** — a hard problem, what I tried, and the fix.
- **Gotchas & notes** — short entries on the small things that cost me a day.

## What I write about

- **Full-stack engineering** — PHP/CodeIgniter, Java/Spring, TypeScript/React, WordPress.
- **DevOps & self-hosting** — Docker, Traefik, Cloudflare tunnels, NAS/unRaid homelabs.
- **AI & automation** — Telegram bots, n8n workflows, local LLMs, memory systems.
- **Web3** — Solidity, Foundry, ERC-20/721 (learning, honestly framed).

## About me

I'm Lee Teong Hoe (Mr Hoelee), a full-stack developer and DevOps engineer
based in Malaysia. I build web applications, self-host a ~140-container
homelab, and run Hoelee Enterprise — a website design & development business
for Malaysian SMEs (with email hosting as a side offering, not the focus).

If you're a recruiter, a client, or a fellow builder — the posts here are my
