United Heroes · Wellness Events
Integrated real-world wellness events into the app so users could discover and join activities without leaving their core product flow.
Partnered with TrainMe instead of building a native events platform from scratch, focusing design effort on a seamless in-app experience.

About
Outside the Interface
Barcelona-based
Product designer who likes systems at work and craft away from the screen.
I recharge through tactile and visual hobbies. Pottery, cinema, books, climbing, and cooking keep me close to rhythm, patience, and detail.
Photography, especially analog, helps me slow down and observe composition, light, and intent with fewer distractions.
