Hi, I'm Catalina.

Front End Developer

I used to think frontend was about making things look good. Then I learned it's about making things feel right. Now, I craft interfaces that listen and adapt to users, stories that stick, and code that welcomes everyone in.

About me

Let me take you through my journey of transformation — from navigating the seas to navigating the web.

The Journey Begins

Life often takes us on unexpected journeys. My path from being a casino dealer and supervisor on cruise ships to becoming a Front-End developer was anything but conventional.

The Transition

Driven by a deep-seated curiosity for technology and a desire for change, I enrolled in an Android development course. This first step into mobile app development opened my eyes to the possibilities in tech.

The Discovery

While Android development was fulfilling, I found my true passion in Front-End development. Learning HTML, CSS, and JavaScript revealed a perfect blend of creativity and technical challenge.

Present Course

Today, I'm crafting digital experiences where creativity meets code. Each project is an opportunity to combine my people skills from hospitality with technical expertise.
