Scope of work

• Implemented LiDAR-based room scanning and measurement capture via ARKit
• Implemented photo attachment as measurement reference
• Implemented project and floor management structure
• Implemented offline-first architecture using SwiftData
• Implemented sync queue for background data synchronization
• Implemented chunked file upload for large scan archives via Alamofire
• Implemented archive packaging for scan data export

Challenges & solutions

The primary challenge was implementing reliable offline-first architecture under tight time constraints with no design assets and poorly defined task descriptions. Built a SwiftData-based persistence layer with a sync queue and NWPathMonitor connectivity detection to transparently handle online/offline transitions. Additionally implemented chunked upload logic for large scan archive files to handle unstable connections and avoid timeout failures during upload.
