• Led complete app redesign from proof of concept to production in 6 months, rebuilding with SwiftUI and The Composable Architecture while splitting codebase into 18 reusable modules for scalability. • Built comprehensive accessibility features meeting WCAG 2.2 AA standards with VoiceOver commands, plus developed turn-by-turn navigation system for blind users featuring intersection alerts and raise-to-activate gesture for pedestrian signal detection. • Refactored CoreML vision pipeline achieving 10× faster performance on A15 devices, 30% battery optimization, and 50% smaller install size while scaling usage from 5,000 to 3 million accident-free street crossings. • Developed internal AI testing platform for real-time model validation, significantly reducing false positive detections and maintaining competitive advantage in accessibility space. • Implemented Mixpanel analytics, secured €80k two-year licensing deal with Blind Association in Toulouse, and mentored junior iOS developer through weekly code reviews and career-growth sessions.

• Led complete codebase migration from Objective-C to Swift in 6 months with 2-developer team, implementing Clean Swift architecture to maximize testability and maintainability. • Evolved MVP into feature-complete application by collaborating with specialized product owners, balancing real estate agent and end-user requirements while maintaining 99.8% crash-free sessions across 100k+ MAU. • Achieved perfect 100/100 accessibility score implementing VoiceOver, Dynamic Type, and high-contrast assets, plus integrated modern iOS features including widgets, Dark Mode, and 3D Flyover. • Automated 539 XCTest/XCUITest cases in Bitrise CI/CD, halving release cycle from four weeks to two while increasing ARPU by 12% through in-app insurance quotes and mortgage calculators. • Coordinated feature roadmaps with Paris engineering squads following SeLoger merger within a larger agile pod structure.

• Led complex database migration for language learning platform, developing C# scripts to transfer data from legacy system to scalable architecture across 30 interconnected tables while maintaining referential integrity. • Enhanced data security and quality by implementing password hashing for plain text credentials, deduplicating records without data loss, and sanitizing Unicode characters for proper string storage following schema best practices.

• Conducted client needs analysis for construction contractors and built complete cross-platform solution including native iOS/Android apps, web application, and cloud backend using C#, SQL, ASP.NET, and Xamarin.Forms. • Collaborated in SCRUM team with developer and designer to deliver MVP within internship timeframe, receiving code reviews and technical guidance from Microsoft professional developers. • Deployed solution on Microsoft Azure with secure database access and API management, successfully field-testing with real construction industry clients to validate platform effectiveness.
