About
My name is Tianxiang, but you can call me Cody. I’m a full stack developer with strong full-stack experience.
On the front-end, I work extensively with React.js and TypeScript to build intuitive, user-friendly interfaces. I also use Redux to manage global state
On the back-end, I develop APIs using Node.js, Express.js, and Spring Boot. I design and implement both RESTful and GraphQL APIs to ensure efficient communication between the front-end and back-end systems.
In terms of databases, I have experience working with both SQL and NoSQL like MongoDB.
Over the past year, I’ve been working at Walmart, where I contributed to refactoring legacy CGI endpoint and implementing email notification functionality to improve system efficiency and communication.
If you’d like to learn more about my experience, I’d be happy to go into further detail. Thank you
