01 — About me

Code is Art, Architecture is Poetry

Hello! I am a backend developer specialized in the Java Ecosystem, passionate about building high-performance, scalable distributed systems. I believe elegant code should not just run, but be clear, maintainable, and withstand the test of time.

In my professional practice, I deeply implement Spring Boot / Spring Cloud microservices architectures, expert in tuning middleware like MySQL, Redis, and Kafka, and continuously explore best practices in the Cloud Native landscape.

In my spare time, I enjoy researching JVM internals, contributing to open-source projects, and sharpening my algorithmic thinking on LeetCode.
