Hi there
I'm Xiaohui Cai (alias Cuthbert at work), a software engineer from China. I started out in the Java world — Spring, MySQL, Redis — and now work across the stack: backend services in Java / Python / Go, Kubernetes, and observability.
This blog serves as a journal for documenting and sharing the insights and knowledge I've gained as a software engineer. Building, writing, and sharing things is a great way for me to solidify my understanding of new concepts and ideas.
I would greatly appreciate any comments and thoughts on my posts .
