iOS consultant and developer with 14+ years of experience, from the first mockup to launch on the App Store. I design and build mobile apps end to end: I define maintainable architectures, set quality standards, and take features from technical specs through to production. I work on large, critical apps inside structured IT departments (media and large-scale retail) and on greenfield products built from scratch. As a technical referent, I carry architecture decisions and help teams grow through code reviews, mentoring and technical interviews, including cross-platform leadership across iOS and Android. My default toolkit is modern and testable: Swift, SwiftUI and UIKit, Clean Architecture and MVVM-C, SPM modularization, automated testing, CI/CD and accessibility. I work closely with Product, Design, Architecture and Backend teams throughout. I invest continuously in on-device AI and the latest Apple APIs through active side projects: a macOS meeting companion (real-time transcription with WhisperKit, summaries via the Claude API), an on-device CRM with fully local AI extraction (Foundation Models, privacy by design), and a local-first habit tracker (SwiftData + CloudKit).…
