About Romain
Backed by a Software Engineering degree obtained in 2010, I have over 15 years of experience developing native applications in Swift and Objective-C within the Apple ecosystem (iOS, watchOS, macOS, and tvOS) as an iOS Mobile Engineer and iOS Tech Lead / Manager.
Now working as a freelance developer, I offer my services to companies and technical teams to design high-performance, robust, and custom applications. My goal: to transform your ideas into high-quality application solutions while meeting the market's most demanding standards.
My areas of expertise and collaboration models:
- End-to-End Support: From analyzing your needs to final deployment on the App Store and ongoing operational maintenance.
- Seamless Integration: Ability to collaborate directly within your teams, adapting to your technical environments, tools, and hardware
- Technical Mastery & Architecture: Designing clean, maintainable, and robust code (SOLID principles, Clean Architecture, etc.) across the entire Apple ecosystem (Swift, Combine, Async, SwiftUI, UIKit, Objective-C, RxSwift).
- Boosted Productivity: Advanced use of modern development tools (including AI assistance) to optimize delivery times while maximizing quality.
