# About Me

​ As an accomplished software engineer with over a decade of experience in software development, team management, and project management, I am equipped with the knowledge and expertise necessary to tackle any challenge in the field. My expertise includes GoLang, Java, and PHP, microservices, distributed services, Blockchain development, popular databases like MySQL, MongoDB, and SQLite, as well as cloud platforms such as AWS, Google Cloud, and Huawei Cloud. I have a proven track record of delivering high-quality results, and I am always eager to learn new technologies and programming languages to stay ahead of the curve.

​ And I will keep sharing what I learned and experience on my personal website.

# Recent Articles

# 1. What is "Reflection" in Java?

​ In Java, reflection is a feature that allows the examination and manipulation of classes, interfaces, fields, methods, and their properties at runtime. It provides a way to inspect and modify classes, interfaces, fields, methods, etc., irrespective of their access level. And we'll dive deep into the core code of reflection, and understand how it is implemented.

# 2. Multi-threading in Java

​ In Java, multi-threading enables concurrent execution of tasks, allowing multiple threads to run simultaneously within a Java program. This facilitates better resource utilization and enhances the performance of applications, especially in scenarios involving heavy computational tasks or I/O-bound operations

# 3. What is "Channel" in Golang

​ In Go, a channel is a built-in type that facilitates communication and synchronization between goroutines (concurrent functions or lightweight threads). It provides a way for different goroutines to share data and coordinate their execution without explicit locking or other synchronization mechanisms.

# 4. Understanding Go's Compilation Process

​ Go's compilation process is a vital component of what makes Go a unique and efficient language. Its blend of fast compilation, effective dependency management, and portability has contributed to its growing popularity in both web development and systems programming.

# Projects

# 1. The backend of Crypto wallet (opens new window)

​ The backend side of Crypto Wallet uses Golang as the main programming language, microservice as the main architecture, and gomobile to generate the SDK for App.

# 2. Java-demo (opens new window)

A demo for Java learning, including some algorithms implementation, basic knowledge, and some advanced knowledge points.

# Get in Touch

Feel free to reach out to me via email at [email protected] or connect with me on LinkedIn (opens new window) and GitHub (opens new window).

I'm always excited to discuss new ideas, collaborate on projects, or simply have a chat about technology.
