以 Java 基础与面向对象为主线，同时整理 JavaScript、NumPy、Pandas 和 Matplotlib 的学习笔记。
熟悉 SQL 与数据库系统理论，包括关系模型设计、查询优化和数据库安全。
参与过仓储管理系统的开发，主要负责审批功能与数据库优化模块。
把知识点条理化整理，再放进真实项目里验证。
学习风格系统化且注重实践。喜欢把知识点条理化整理，并通过实际项目应用所学；笔记里能看到对技术细节的关注和对原理的追问。
注重知识的系统性学习与积累，善于分类整理信息，也热爱分享——这个博客就是这样长出来的。
我是 Taylor Swift 的忠实粉丝。除了编程，也喜欢通过博客分享知识、记录学习心得。

I'm Yuanshan Jiang Jinyue (LuckyE), a master's student at the University of Shanghai for Science and Technology (USST), researching reinforcement learning. I love computer science and building software, with a systematic grounding in Java. This blog covers programming languages, backend systems and databases, reinforcement learning and RLHF, and AI-agent-era software engineering.
Java fundamentals and object-oriented programming, alongside JavaScript, NumPy, Pandas and Matplotlib notes.
Familiar with SQL and database theory, including relational model design, query optimization and database security.
Hands-on experience building a warehouse management system, focused on the approval workflow and database optimization modules.
Organize what you learn into a structure, then prove it in a real project.
Systematic and practice-oriented. I like turning knowledge into structured notes and applying it in real projects; my notes show an eye for detail and a habit of asking why.
I value building knowledge systematically, I'm good at sorting and organizing information, and I love sharing what I learn. This blog grew out of that.
I'm an avid Taylor Swift fan. Beyond programming, I enjoy sharing knowledge and keeping notes on what I learn through this blog.
