What I'm looking for

I'm open to US-based roles as a contractor or through EOR, with overlap in US time zones (EST–PT).

At BairesDev, working with client TextNow, I improved app stability to 99.8% crash-free sessions and re-engineered the messaging pipeline to reach 99.5% delivery success. I also used foundation models to generate context-aware message replies.

At Unosquare, working with client Stitch Fix, I modernized UIKit screens with modular SwiftUI components and accessibility support, while introducing snapshot tests and feature-flagged rollouts. At Kenility, working with client TruVideo, I designed and published modular iOS SDKs and automated their testing and distribution.

At Jalasoft, working with client ECI Solutions, I led the shift from a monolithic iOS codebase to a modular SPM architecture and expanded automated unit test coverage from 20% to 70%. Earlier at Viva, I maintained native iOS modules in Objective-C and improved responsiveness by reducing critical UI hangs.
