Mobile / iOS

iOS Engineering

Production Swift engineering across two distinct domains: clinical research (Columbia University Language & Memory Test) and AI / mobile / property tech (MakenaAI). Full-stack iOS — Swift, SwiftUI, ARKit, REST APIs, XCTest, and App Store delivery.

Overview

iOS engineering is a distinct technical track built through real production systems with non-trivial constraints. The Columbia work required HIPAA-adjacent security considerations for clinical research data and cross-cultural accessibility for global patient populations. The MakenaAI work required real-time AR rendering and a subscription payment system that had to work reliably for 2,000+ paying clients on day one of launch.

The full stack: Swift and SwiftUI for UI, ARKit and RealityKit for the MakenaAI AR pilot, XCTest for unit and UI testing, REST API integration (Flask at Columbia, FastAPI at MakenaAI), and App Store submission compliance.

Projects

Research / Clinical

Columbia Language & Memory Test

Full-stack iOS app for a Columbia University neuroscience research lab. Published in The European Journal of Neuroscience. Advised global clinical pilots reaching 4,000+ patients across Africa, Europe, and Asia.

Enterprise / Property Tech

MakenaAI Appraiser Platform

Enterprise iOS platform for real estate appraisers. Built the subscription and payment system that onboarded 2,000+ clients within one week of launch. Led the "Digital Clone" AR pilot for remote property inspections using ARKit.
