The Short Version

I’m Bruce. I write about AI engineering — the kind of stuff you actually need when building with LLMs, not the hype.

10+ years building backend systems (Java, Go, cloud-native). Since 2024, fully focused on AI: coding agents, multi-agent architecture, and making AI tools work in real projects.

This blog has 150+ articles. Most of them are the guides I wished existed when I was figuring things out myself.

What You’ll Find Here

Honest tool reviews — I’ve tested Claude Code, Cursor, Codex CLI, Kiro, Google Antigravity, and more. Not “Top 10 Amazing Tools” listicles. Real benchmarks, real trade-offs, real recommendations.

Step-by-step guides — From setting up your first AI agent to deploying multi-agent systems. Complete code, tested workflows, copy-paste configs.

Comparisons that save you time — Claude Code vs Copilot. TypeScript vs Python for AI. OpenClaw vs CrewAI vs AutoGPT. I do the research so you don’t have to.

Hard-won lessons — 15 OpenClaw automation mistakes I made. MCP security vulnerabilities nobody talks about. Context engineering pitfalls that waste your tokens.

How I Write

One rule: every article starts from real usage, not speculation.

I use the tools, run into the problems, figure out the solutions — then write it up. AI helps me write faster and more clearly, but the experience and judgment behind each article are mine.

I also don’t bury the answer. If you’re here for a specific solution, you’ll find it fast.
