NASA Explorer
A SwiftUI app for discovering NASA’s Astronomy Picture of the Day
and exploring space imagery from NASA’s media library.
Problem
NASA provides multiple public APIs, but their content is spread across
different services and can be difficult to explore from one mobile experience.
Solution
Built a polished iOS app that combines NASA’s daily astronomy content,
searchable media library, detailed image views, and saved discoveries
in one accessible experience.
Architecture
Built with SwiftUI and MVVM. Observable view models manage UI state,
service types handle networking, Codable models represent API responses,
and SwiftData provides local persistence.
Technical challenges
Integrated two NASA APIs with different response structures, handled
image and video APOD content, decoded nested JSON, managed asynchronous
loading states, and displayed remote media reliably.
Tradeoffs
Used AsyncImage for straightforward remote-image loading and SwiftData
for lightweight on-device persistence. More advanced image caching and
offline synchronization are planned improvements.
Results
Delivered a reusable, API-driven SwiftUI application with clear separation
of concerns, persistent saved content, responsive loading states, and a
polished space-inspired interface.

My role
Designed and developed the complete iOS experience, including the user
interface, MVVM architecture, API integrations, data models, persistence,
error handling, and visual polish.
Recruiter takeaway
Demonstrates my ability to build a production-style SwiftUI app that
integrates real-world APIs, uses async/await, manages application state,
persists user data, and presents complex content through a polished UI.
