Project Overview

The Isar App is a real-world iOS application built with React Native for performance, clean architecture, and a consistent UI. It is live, actively used, and maintained through a structured development process within a product team.

Technology Stack

• React Native (iOS-focused): Core framework for Apple devices, delivering native-like performance and smooth UX.
• TypeScript: Strong typing across the codebase to reduce runtime errors and improve maintainability.
• React Navigation: Ensured consistent and intuitive navigation between screens.
• Expo: Streamlined development and simplified iOS deployment.
• ESLint & Prettier: Enforced clean and consistent code via pre-commit hooks.

Development Highlights

• Worked within an agile team, implementing features and improvements via assigned tickets.
• Built modular UI components and reusable hooks for scalability.
• Followed best practices for version control, code review, and linting.
• Performed regular testing on real devices to ensure stability and user satisfaction.

In this project, I worked on an iOS app in a product team. The hard parts were adding a React calendar, making sorting work well, and optimizing images, text, and PDFs so file size was smaller. I solved these with React Native tools, custom hooks, and good optimization practices.
