Biography

I am so excited you are interested in getting to know me!

I am born in Beijing, China. Growing up this busy, metropolitan city, I became fascinated by the power of technology, particular by computers, and became obsessed with solving puzzles and math problems since then. In 2015, I came to the United States for high school and began my journey into the world of science and engineering. Now, I am a senior Math & Computer Science & Statistics major at the University of Illinois at Urbana Champaign. With a B.S. in highly interdisciplinary fields and four internships of hands-on software engineering experience, I am confident that I'd be a strong addition to your company.

I worked as a software engineering intern at Foxconn in Mt. Pleasant, Wisconsin for the past three summers. In my first two intern period at Foxconn, I was responsible for developing an enterprise website using Django and PostgreSQL database for the company’s ERP purposes. I implemented the Python backend for handling approval processes, forms application, resource allocations, and many other HR daily tasks using Django ORM. In my last internship at Foxconn, I developed APIs using FastAPI that bridge communication between the production line and SAP, Shopfloor, and our clients (Google). I also used many developer tools daily, in including Docker, git, Linux Bash, Postman, AWS, and various IDEs and management system for databases (pgAdmin, Oracle SQL Developer, dBeaver).

Before working at Foxconn, I was a web development intern at China Taiping Insurance, Hubei, where I was primarily responsible for developing a Java-backend customer-complaint management system with Oracle database, deployed on Apache Tomcat. I also assisted in fixing bugs, implementing UI enhancements, using HTML, CSS, Ajax, and JavaScript (jQuery) to build and enhance web pages. In addition, I helped design the database schema for the customer complaint management system.

Interning at these companies provided me the opportunity to put my computer science knowledge to work — developing and testing products for the marketplace. At both Foxconn and China Taiping Insurance, I demonstrated my ability to hit deadlines, maintain strong attention to detail, and produce top-notch, maintainable code. I’m confident my skills will be put to good use in the software engineering industry, and I look forward to speaking with you further about relevant positions.
