Technologies & Tools: React Native • TypeScript • Firebase (Crashlytics) • Zustand • React Query • AsyncStorage

• Maintained and modernized 17+ legacy React Native applications for Domino's Pizza across multiple countries, delivering new features and ensuring consistent performance and reliability at a global scale.
• Led end-to-end feature development across a multi-region app portfolio, adapting business logic and UI to meet country-specific requirements while preserving a shared codebase architecture.
• Conducted systematic legacy codebase refactoring and dependency upgrades, reducing technical debt and unblocking new feature development across all regional apps.
• Collaborated in a fully English-speaking, international environment within a global consulting engagement, communicating effectively across distributed teams and stakeholders.
• Delivered performance and stability improvements across production apps using Firebase Crashlytics, maintaining high availability standards for a high-traffic food ordering platform.
• Applied state management and offline-first patterns [Zustand, React Query, AsyncStorage] to ensure resilient user experiences across varying network conditions in multiple markets.

Technologies & Tools: React • React Native • ASP.NET • TypeScript • Firebase (Crashlytics / Remote Config) • Zustand • AsyncStorage

• Launched a flagship React Native application from 0 to 1, scaling to 100,000+ downloads while maintaining high performance across 80+ screens.
• Engineered performance optimizations (R8, obfuscation) that slashed bundle size by 20%, directly improving user retention and app store visibility.
• Integrated 30+ RESTful API endpoints and instrumented Firebase Crashlytics and Remote Config, ensuring high availability and rapid error resolution in production.
• Architected client-side state management with Zustand for global stores, React Context API for scoped providers, and AsyncStorage for persisted user data, improving predictability and offline resilience across the app.
• Shipped features and performance improvements (lazy loading, bundle reduction) on a high-traffic web platform serving 200K+ monthly visitors and processing 1,000+ monthly orders.

• Gained deep understanding of Agile methodologies (Scrum/Kanban) by rotating through critical roles including Scrum Master, Product Owner, and Developer during initial sprint cycles, enhancing cross-functional collaboration skills.
• Executed end-to-end UX/UI activities, ranging from user research, persona creation, and usability testing to designing high-fidelity wireframes and prototypes using Figma.
• Designed user-centric interfaces for two mobile products: a legal marketplace connecting lawyers with clients and a delivery application for a pizza chain with multiple branches, focusing on usability and conversion flow.
