iOS Specialist at Globo, working on Cartola FC, the largest fantasy football game in Brazil.
I design and ship native Apple products for millions of users. My work sits at the intersection of Swift/SwiftUI engineering, modular architecture, design systems, and AI-augmented development.
- Lead iOS development for Cartola FC
- Build modular Swift packages with SPM
- Design component systems and design tokens
- Ship CI/CD pipelines and automation for mobile teams
- Turn product ideas into working native apps

- Native first — platform APIs before cross-platform shortcuts.
- AI-augmented — AI accelerates the craft; humans own the outcome.
- Design = architecture — spacing, motion, typography, and interaction are engineering decisions.
- Ship, then polish — working software in production beats perfect branches.
