About Antoine
Product-focused iOS engineer with extensive experience building, scaling, and shipping high-quality mobile applications, both independently and within cross-functional teams.
I help companies design and develop robust, performant, and user-centric iOS apps, from early concept to App Store release. I have worked on consumer apps used daily by millions of users, as well as business-critical and data-intensive products, with a strong focus on quality, scalability, and long-term maintainability.
My expertise covers the full mobile lifecycle: architecture, SwiftUI & UIKit development, performance optimization, onboarding and growth features, analytics, monetization, and App Store delivery. I collaborate closely with product, design, and backend teams to turn product vision into reliable, impactful solutions.
Available for freelance missions on new projects, scaling existing apps, or strengthening mobile teams with a senior, autonomous profile.
