A live project running for 8 years, developed by multiple contractors with inconsistent approaches Instability across platforms: Web, iOS, Android (phones & tablets), Admin, Manager, and Courier apps Issues included frequent crashes, poor navigation, drag-and-drop bugs, hardcoded values, low-quality animations draining device resources, and degraded performance No clear documentation or requirements, making redevelopment and migration risky Client needed a new, stable architecture to handle growing traffic and ensure smooth performance on lower-end devices Urgent delivery required to prevent customers from leaving due to poor app experience

Designed a robust application architecture for Web and Mobile, ensuring scalability and stability Rebuilt core apps: Ordering App (customers), Courier App (couriers), and Manager App (restaurant managers) Integrated seamlessly with the existing backend, despite lack of documentation Improved UI with modern styles and added animations using React Native Skia Implemented performance optimizations to double speed while supporting older devices Ensured smooth migration process to retain the existing user base

Increased overall app performance by 40% and reduced content loading time by 50% Achieved zero bugs in production Stabilized courier geolocation tracking to 99% accuracy Rolled out 12+ new features and integrated 3 essential tools Implemented Firebase Analytics, providing actionable user insights Enhanced UI, improving user satisfaction by 25%
