Hi, I'm
Alex Rivera

A full-stack developer and designer with a passion for crafting elegant digital experiences. I believe great software is as much about feel as it is about function.

When I'm not pushing pixels or writing code, you'll find me exploring city streets with a camera, contributing to open source, or brewing the perfect cup of pour-over coffee.
