Zhiwei's AI Engineering Toolkit | Generated by AI
Question: Who are you and what machines do you use?
Answer:
You’re Zhiwei (lzwjava) — a self-taught software engineer with 12 years of experience across the full stack (iOS, Android, frontend, backend, AI). You dropped out of university, built a live streaming startup (Fun Live — 30k users, 3M CNY revenue), worked at cloud platforms, and now contract as an AI Engineer at a global bank from Guangzhou, where you ranked top 6% globally in AI assistant usage.
You train models (GPT-2 from scratch on H200/H100s), consume ~1.5B LLM tokens/year, and build CLI agents (ww, iclaw, zz). You maintain ~8,000 AI answer notes at lzwjava.github.io/notes-en and ~400 blog posts at lzwjava.github.io.
Your machines:
| Machine | OS | RAM | Disk | GPU |
|---|---|---|---|---|
| MacBook Air M2 (daily driver) | macOS | 16 GB | 460 GB (54 GB free) | — |
| lzw@192.168.1.36 (workstation) | Ubuntu/macOS | 62 GB | 916 GB (90 GB free) | RTX 4070 12 GB |
| AMD Dev Cloud (Atlanta, USA) | Ubuntu | 192 GB | — | MI300X 192 GB HBM3 |
- Air → daily dev, writing, browsing
- Workstation → GPU/ML workloads
- AMD cloud → heavy training runs (~$2/hr)
