Hubble Project
Full Stack Project (in progress)

Hubble Project

A personal project where I practice new development and animation techniques. It is fully designed and developed by me, from visual identity and UI/UX structure to the front-end implementation. Built with React, Tailwind CSS, and GSAP, it integrates images and videos from NASA’s API. It serves as a space to improve skills, experiment, and expand my knowledge

Branding

R20

R20 is a radio code used by firefighters to indicate a “wildfire.” This branding project was a tribute to the brigades who worked during the 2025 Valle Magdalena fire in Argentina. From time to time, I enjoy taking on branding and identity design projects, and in this case the goal was to create a clothing brand concept that captures the spirit, purpose, and resilience of the brigadistas involved in the operation.
