Sean Coughlin portrait
👋

Hello, I'm Sean. I'm a full-stack developer with 3 years of experience. I enjoy building sites & apps. My focus is web development.

About me

I have my undergraduate and graduate degrees in computer science. I am currently a full-stack web developer with Discover. My favorite part of programming is seeing creations come to life. I love the feeling of finally shipping code.

My core stack is React, Next.js, Java, and Spring Boot. I am also familiar with TypeScript and cloud development. I am always looking to learn new technologies. Currently, I am studying for cloud certifications.

When I'm not coding, I enjoy working out, hiking, exploring National Parks, and reading.
