About

Hi, I’m Bruce — an engineer with 10+ years in backend systems, now fully focused on AI engineering.

I’ve built and scaled backend infrastructure at multiple tech companies, working across Java, Go, and cloud-native stacks. Since 2024, I’ve gone all-in on AI — from LLM application development to AI Agent architecture, accumulating hands-on production experience.

What This Site Covers

This site publishes practical, in-depth guides on AI engineering topics:

• AI Coding Tools — Claude Code, Cursor, Codex CLI: setup guides, best practices, and real-world workflows
• AI Agent Engineering — Agent architecture, multi-agent orchestration, automation workflows
• LLM Application Development — RAG systems, vector databases, prompt optimization
• Tool Comparisons — Head-to-head evaluations to help you pick the right tool

The site also retains earlier technical notes on Java, Go, Docker, and Linux (written in Chinese) as archived content.

Why This Site

AI moves fast. Writing forces clarity. Every article is based on real usage, tested workflows, and verified results — not speculation.

If you find the content useful, share it with someone who’d benefit.
