Architected a 3-tier application ecosystem (Driver App, Business App, and Web Admin) using React Native/Expo and Spring Boot, enabling seamless job matching for 100+ concurrent users during peak rush hours. Engineered a real-time communication layer using Firebase Cloud Messaging (FCM), achieving a 99.9% notification delivery rate and reducing worker response times by 70% (from minutes to seconds). Developed a high-performance backend with Spring Boot and Maven, implementing RESTful APIs optimized for mobile clients with TanStack Query to ensure data consistency and offline caching. Optimized mission-critical SQL Server queries for real-time driver availability, reducing database search latency by 45% through the implementation of Stored Procedures and Non-Clustered Indexes.

Architected a native iOS academic ecosystem using SwiftUI and CoreData, implementing a multi-view organization system that allows students to filter assignments by Date, Priority, Subject, and Completion status. Engineered a seamless cross-device synchronization layer using NSPersistentCloudKitContainer, ensuring real-time data continuity and conflict resolution across all user devices signed into iCloud. Developed a high-visibility productivity suite by integrating WidgetKit for 'at-a-glance' home screen tracking and a custom Local Notification system that proactively alerts users to upcoming deadlines. Secured sensitive student data by implementing a local authentication system using Keychain Services for token storage and CryptoKit for salted password hashing. A clean and simple Hugo template for personal portfolio and blog.

Designed a versatile habit-tracking engine supporting six distinct data types (Boolean, Numeric, Duration, Checklist, Streak, Periodic) to accommodate diverse user goals and measurable behavioral changes. Integrated a sophisticated mood-correlation system featuring 20 distinct emotional states, allowing users to visualize the relationship between mental well-being and habit consistency through interactive charts. Implemented an advanced visual analytics dashboard using the Swift Charts framework, providing users with heatmaps, trend lines, and completion rate statistics across weekly, monthly, and yearly intervals. Leveraged SwiftData and CloudKit to build a modern, reactive persistence layer that automates data synchronization while maintaining a zero-latency, offline-first user experience.
