Hi, I’m Liu Chen, a seasoned software developer with a passion for building reliable, scalable back-end services and intuitive front-end tools. Over the past decade, I’ve contributed to desktop applications using Java Swing and to modern cloud-native backends with Spring Boot and microservices, always focusing on performance, security, and maintainability. I enjoy solving complex problems across the full stack, from designing data pipelines with Hadoop/HBase to implementing robust authentication with Spring Security. When I’m not coding, I like sharing knowledge with teammates and exploring new technologies that can improve product quality and user experience.…Hi, I’m Liu Chen, a seasoned software developer with a passion for building reliable, scalable back-end services and intuitive front-end tools.
