01 — INDEX
Guillermo Cartagena — a software engineer based in El Salvador. I design and develop clean, scalable web products, and on the weekends I get away with my camera, cycling, or running.

ABOUT
I work with React, Next.js, Laravel and PostgreSQL. I care about responsive, accessible interfaces, type that reads well and stays out of the way, and code that other people can read. On the road or the trail I find the kind of rhythm that keeps the mind honest — no scoreboard, just breath and forward motion. I think in layers, and I've learned that listening well is its own kind of craft.
02 — WHAT I DO
Clean, modern interfaces — optimized for performance, SEO, and turning visitors into users.
Backend and product logic shaped around real user needs, not framework fashion.
Responsive by default. Your work should reach every screen, every reader, everywhere.
