Professional profile

Mobile development.
AI applied to products.

I'm a computer engineer working in iOS development since 2022. My experience spans retail, banking, loyalty and workforce applications built with Swift, SwiftUI and UIKit.

At Mercado Libre, I work on the Mercado Pago experience: navigation, reusable components and design systems. Previously at Mobilenik, I developed features and maintained production apps for clients in Argentina and the United States.

In my own projects, I handle product decisions, implementation and release. In PetFamily, I work with Foundation Models and prompt design to generate contextual insights from each pet's records.
