Hello! I’m Luis Montero.

Full Stack Developer based in Costa Rica.

About.

Hey! I’m a 21-year old developer who’s been building software for the past 3 years. I’ve worked on everything from sleek frontends to backend APIs and even some Web3 experiments along the way.

I’m also a startup founder. My proudest project so far is Katalogue a startup I co-founded and led as the tech lead. I was responsible for driving the engineering side, from architecture to implementation, always aiming for clean UI, thoughtful UX, and solid technical foundations.

Whether I’m building a new product, leading frontend work, or just tinkering with a new tech stack, I’m always driven by curiosity and a genuine passion for creating things that matter.
