Sobre
iOS Engineer with 10+ years of experience building and evolving mobile products, with a strong specialization in UIKit and SwiftUI.
I bring an architectural and product-oriented mindset to developing scalable, high-quality, user-centered experiences across
Apple platforms. Open to full-time opportunities, consulting, and long-term company-to-company collaborations.
My background includes working on large-scale, high-impact products,
such as one of the largest financial “super app” in Brazil, which is used by over 30 million users. In this role, usability, performance, and reliability were critical at scale. More recently, I contributed to a global agribusiness application at Valmont Industries, modernizing legacy codebases, improving visual usability and field workflows,
and upgrading the project to newer Swift and Xcode versions while adopting the latest Apple platform capabilities.
As Lead Mobile, I coordinate team workflows, drive feature development, and ensure system stability through monitoring,
code reviews, and continuous improvements. I actively mentor junior developers, collaborate with product and design teams, align technical solutions with business needs, and lead critical deliveries in high-pressure “war room” scenarios when needed.
This combination of hands-on development, technical leadership,
and architectural thinking allows me to guide projects beyond implementation, balancing delivery speed with long-term sustainability.
I have also led teams in competitive, high-intensity environments,
earning recognition in Brazilian and international hackathons,
reinforcing my ability to deliver quality solutions under tight deadlines and demanding standards.
