UruguayWhat I'm looking for
I’m a Senior iOS Engineer with 15+ years of experience building and scaling mobile applications for top tech companies and startups, including MercadoLibre, Booking.com, and Abra. I specialize in Swift, Objective-C, and SwiftUI, with a strong focus on mobile architecture, performance optimization, and UI/UX best practices. I bring a product mindset to deliver high-quality, scalable solutions using agile methodologies and modern development practices.
I’ve led distributed teams and influenced technical direction—coordinating code reviews, release cycles, and standardizing best practices across engineers. At MercadoLibre, I contributed to iOS apps used by tens of millions of users and built a SwiftUI-based UI Library to improve development speed and UI consistency. At Abra, I led a team of six engineers, drove major product upgrades for stability and UX, and mentored junior developers, while also shipping from scratch with architecture, CI/CD, and API integrations across iOS and Android.
