About me

With strong logical thinking, I have won the second prize of China Mathematics League at provincial level and the top 1% of AMC mathematics Competition in the United States.

I am an experienced computer science student with a strong passion for software engineering and full-stack development. Currently I have graduated on May 2024 with a Bachelor of Science degree in Computer Science at the University of Southern California. With a GPA of 3.87, I have consistently demonstrated a commitment to academic excellence.

Throughout my academic journey, I have gained valuable industry experience through multiple internships and projects. These experiences have allowed me to develop a diverse skill set and a deep understanding of various programming languages, frameworks, platforms, databases, and tools. I am proficient in C/C++, Java, Golang, Python, JavaScript, CSS, HTML, PHP, Swift, as well as frameworks and platforms such as Laravel, Spring, Hibernate, Docker, Bootstrap, EC2, Kubernetes, React.js, Vue.js, Maven, and Gradle. Additionally, I have hands-on experience with databases like MySQL, PostgreSQL, MongoDB, Firebase, and Elasticsearch, and tools such as Apache Tomcat, Nginx, Git, JUnit5, and CI/CD.

I hope to become an excellent full-stack development engineer after graduation.
