Liu Bo

A backend-first engineer based in China.

I focus on Java/Spring backend systems, production debugging, and reliability — with experience spanning from mobile features to DevOps tooling.

What You’ll Find Here

• Production incident write-ups — What broke, why it broke, and how it was fixed
• Backend and reliability notes — Patterns, pitfalls, and trade-offs from real systems
• AI tooling experiments — Practical ways to improve engineering workflow

Why Write

Most engineering problems aren’t new, but useful context is often scattered.

If these notes save someone a few hours of debugging, that’s good enough.
