Hi, I'm Alex Rivera
Full-Stack Developer
I build clean, modern web apps with React and Next.js. Currently looking for full-time and internship opportunities to grow as an engineer.

A developer who loves building things
I'm passionate about turning ideas into clean, usable web apps — and I'm eager to bring that energy to a great team.
I'm a full-stack developer and Computer Science student who loves the craft of building for the web. I've built everything from small UI experiments to full-stack apps with React, Next.js, and TypeScript.
I care about the details that make software feel great — clean code, thoughtful design, accessibility, and performance. I learn fast, love feedback, and enjoy working with others to ship things people actually use.
Based in San Francisco, CA and open to relocation. When I'm not coding, you'll find me contributing to open source or writing about what I learn.
