Senior iOS Engineer • SwiftUI • SwiftData • iPadOS • Performance
Senior iOS Engineer and technical leader with 10+ years of experience, including 5+ years architecting large-scale enterprise iPad applications. I focus on clean SwiftUI architecture, strong data layers, and measurable performance in production-critical systems.
Focus
What I build
SwiftUI Architecture
MVVM, shared app state patterns, modular design, maintainable UI composition.
Data & Persistence
SwiftData / Core Data, caching strategies, efficient querying and data flow.
Performance
Large lists/grids, view decomposition, reduced recomputation, main-thread minimization.
Modern iOS Integrations
Widgets, App Intents, notifications, background processing in secure enterprise environments.
Work
Featured projects

Details are described at a high level due to enterprise confidentiality.
HealthWay Digital
A healthcare-focused digital product experience (portfolio item).
- Showcases clean architecture, modular UI, and strong UX fundamentals.
- Structured as a product-style case study with clear problem/solution framing.
- Great candidate for screenshots and a short walkthrough video/gif.
Send me 4–6 bullets of what it does and I’ll turn this into a stronger case study with no fluff.
